ok just took my 1991 n/a rx-7 to the shop and the guy just called me and said the throttle body was ruined from the tps sensor being adjusted wrong and it needed an oil metering pump(?) and it will be 2000 dollars to fix... the guy my step dad got it from said they hooked it to a machine and it said the tps was bad... thats it. is the dealer trying to rob me? he said its like 500 bux for a used throttle body(i have one at home complete i paid 70 for with sensor on it) and 900 for a used oil metering pump and the rest is in labor... i dont know crap but i never had a running car that took 2000 to make run right that was 10+ years old. any input or info would help...

thanks

yes they are robbing you blind. drive or tow it out of there and find a local reliable rotary mechanic.


typical behavior at dealers... can't figure out the problem the request everything suspect be replaced and hope to scare the customer off, if the customer pays the bill then the problem is still fixed but at a cost that is way more than should be due to parts replaced that never should have needed to be.

eugenius

that does not exsist... im from the boonies... my rx-7 is the only one registered in my county. all the mechanics turned it down already. when i told the guy 2000 was unexceptable, we talked a lil, said to put my tb on and tune in the tps it would be 130, i just found a oil metering pump for 250, so i gotta ask them for a price on labor on that. i got 2000 bux but it aint going to for repairs, it needs slight body work, i had set 1000 for repairs, 600 for body and paint and 400 ish for aftermarket stuff. anything under the 1000 was also going on aftermarket.

You can get a TPS for like, uhh, $20-40 here on the form. Plug-n-play.

You're TB BASICALLY can't get "ruined". And in NO WAY can the TPS ruin the TB.

If you want to avoid a bad OMP, which, at this rate, they probably lied about that, you can just remove the whole system and premix. I would do this before replacing an OMP anyday. I'd remove mine, but it works right now


What did you take the car in for in the first place?

Did you take it to Mazda? Those are LUDICROUS prices, even for a dealership. If it's just a basic automotive shop, you need to get your Step-Dad to go in there and kick some ***! Those guys are literally attempting to bend you over and ram a tire-iron IDB, without lube.

First of all I doubt you have a "bad" TB. Second, someone will sell you a used TB for less than $50 in the FS section. Third, you can find an OMP setup for like, several dollars to $50 as well... Although, if you're replacing the OMP lines, it's smart to replace them with some nice SS (braided Stainless-Steel) lines (available at Mazdatrix.com for around a $100 or so).

I guess the BEST question to ask in this case is: What is wrong with your car? What are the symptoms? Please describe EVERYTHING in meticulous detail that is wrong with your Rx7... This forum will be your mechanic. Or, better yet--this forum will make YOU your mechanic.

i took that rout, trying it myself, i got a tps for 70 off ebay that came with a tb. put tps on and it didnt fix anything. i tryed to adjust the tps myself but couldnt figure it out and set it back like it was. i got really frustrated and took it in to the dealer this morning. i really like the car and really want to get it running asap so i figured since i got the cash let some one else do it. i ordered a shop manual for it today. i wanna learn to mod and tune it myself but i needed it going now. im not super savy on cars so id need dummy instrutions which is hard to find. i didnt wanna try to fix more problems myself with 0 sucess and just waste money. really sucks the dealer was giving me the because he said he could have it running right by wed.

Not an S5 TPS for that? They're expensive but not 2000 dollars. I don't think you can completely remove the OMP either on an S5. Throws the ECU off.

You are suffering from crooked *** bithes trying to rob you. YOu shouyld reprot it to the better business bureau. Trottle body bad? I dont think so. TPS? absolutely. Those are notorious for going out. I never had one that lasted the life of the car. YOU can check the forum for a used TPS and hope like hell it works. Or you can order one from Mazda and pay a pretty penny. I hate hearing stories of this, I needed a rebuild on my vert sometime ago and Mazda wanted 5800 freekin bucks to gimme a reman. But if its any consolation, even though you dont live in a town where theres any reputable rotary mechanics, you should feel comfortable knowing you have always got the forum for advice. At least were not going to sodomize you in exchange for advice, well at least I wont. Homey dont play that ****.

can i get some info on premixing? and is there a way i can check and see if the oil metering pump is bad? i dont wanna premix if the car is doing it. i dont know if the tps is bad. i got one off ebay and it didnt change anything. i guess the one i bought coulda been bad too. also how hard is it to change out an oild metering pump? if mines bad ill premix, and maybe swap out later if premixing is anoying. thanks for all the help guyz

Is your check engine light going off? Pull the codes and tell us what it says.

Where is Sealy?

eugenius

the check engine light isnt on when i 1st start it, only after im driving for a min or so. how do i pull codes? and sealy is ummm, off i10, it near columbus. west of houston. 77474 is the zip if that didnt help.

matts86fc3s

holy **** they are bullshitting. punch the guy in the face. hahahahaha... how is a misadjusted tps going to ruin your throttle body??? and you might need an oil metering pump who knows... but 2k???? good god you can buy a complete running T2 car for that on ebay... dude your getting shafted

kenn_chan

E,

first I need to make two assumptions here they are that you have the nesseary hand tools, and that you know what the OMP looks like.

that being said, its eay to check, first fill your gas tank and premix in .5 quarts of two stroke oil with the gas (this is for safety purposes only, but do it)

there are 4 hoses that attach with banjo bolts to the OMP. start car, idle until normal temps have been reached. shut off, and pull off the two lower, hoses form the OMP. jerry rig two hose's from the pump to a small container. start the engine and rev to 2000 rpm for 1 minute. you should be able to measure 6 cc's of oil. reattach the two hose's and do the same for the top two hoses, you should now have a total of 12 cc's of oil. (it will vary from 8~16 cc, with 12 being perfect) more will not hurt, but less than 8 is dangerous. if it passes this test tell the STEALERSHIP TO SUCK YOUR LEFT NUT and then offer them the right nut for their 16 year old daughter to fondle and dream about

kenn_chan

If it doesn't pass the test, get one of the members here to send you an OMP, it takes 10 minutes , two skinned knuckels, and a small amount of RTV to put it back on.

dang,sounds like you better call that dealer ship and ask them if they have fire insureance.....

renegade_gxl

dude your in the same boat as me..i aswell dont have access to a rotary mechanic. at least not easily in any sence. my suggestion is that if you have a friend of the family thats a mechanic, weather its heavy duty or just straight vehicle. ask if he will help you.. even if he dosent know much about rotarys as long as you got a shop manual for your car then he will be better then nothing..and you can find the shop manual online. i suggest that you do most of your own work then and if not have the mechanic help or supervize and throw suggestions at you.. thats what ive done and ive faced only minor problems..the only thing i wouldnt let him do is go into my motor with out me there. that way if something gets messed then you still have yourself to blame... anything else id welcome the help.. and it will more then likly only cost you the parts that are needed..

and yes the board can and most likly will walk you through pretty much anything youll need to do to your car..most of us are more then willing to lend a hand in what ever way we can.

just speaking from personal oppinion and experiences.

If you find out that you FOR SURE need the TPS you can PM me. I have one that was pulled from a working S5 with about 95K on the odometer. By the way the TPS I have I believe is still mounted to the throttle body (I`d have to pull the box and check)
Let me know if I can help.

I know where Sealy is, I grew up in NW Houston (Spring Branch)

Sorry to hear you're getting jerked around. Both the TPS and OMP are not difficult to deal with, but it sounds like you have other system level problems.

The OMP, just start premixing for now and don't worry about it. Just how did they come to the conclusion the OMP is bad--the only way to know is take off the lines and see the oil come out.

The TPS is easy to check, just get yourself a $10 radio shak digital volt/ohm meter and sweep it out.

My bet is you got other problems though. These guys are right--the rotary isn't that different from other cars--at least at the troubleshooting level. So just find a good mechanic--or better yet learn to do it yourself--you'll be glad you did.

Good Luck, HTH,

Scott

called em this morning.... he strong suggests not to premix.... hed much rather the 2000 to fix it. what an a$$. said a do not adjust screw was adjusted on th TB. said it had to be set to factory specs or it wouldnt work right so hed have to put one on from mazda. said that it was suposed to have a goupe on it and mine didnt. said he couldnt adjust my TPS with that like that.... going to go get it now. if i have drove it over 250 miles with out premixing and it still runs just as shitty as when i bought it, should i premix now or should i check it 1st. i gotta put another 100 miles on it or so today

Damn, if I would've read this thread sooner I'd of helped you out. I was about to be in Houston today/tomorrow but I passed since I had nothing to do there. If you've got AIM shoot me a message (SN is SonikRaT)

shes home... guy wanted 85 dollars for the diagonose... guess if i payed him? well a guy at MAZMAX told me that im the OMP goes out, it will fry out the comp, causing my car to mess up like it is. think im gonna get a new ECU and OMP and alot of help from this forum and do it myself. even the guy from mazmax said to do it myself its alot cheaper. still have no clue what he meant on the TB being messed up, i dont see the screw hes talking about. any input on this? thanks for all the help guys. 2000 richer now

SonicRaT

iTrader: (6)

That's not always true (I'd say about 30% of the time or less). Also, if your OMP was bad, you'd never get the car to go passed about 3K rpm in gear, it'd feel like it ran straight into a brick wall. Like I said, shoot me a message on AIM and I'll see if I can help you out, I'm not too far away.

that doesn't count then
