did you check for vaccuum leaks? All the grounds are ok? CAS, AFM and hoses are all connected? check the TPS to make sure it's within specs.

double check your work and figure out which hose/wire you forgot to plug in. It should be plg and play.

 

hmmm

 

just hmm. you could have at least lied and said you had a similar problem if you wanted to post *****. I hate this forum.

 

well thats where i have run into my issues i have doubble checcked all my vacume lines i even swithced a few around thinking i may have accedenaly got them crossed no go it still acts the same and the the tps was acting perfict all i did when i pulled the engine out is un bolt the throtle boddy and set it to the side i didnt mess with any of its adjustments i have been at this for a week solid before i finaly broke down and asked for help today. i do apreciate the feed back though any more would be greatly apreciated thanky you all in advance for your time and help .

 

now my exaust isnt bolted to the manafold right now im still waiting for the exhaust gasket to come in would that cause it to act this way? all my grounds are good . and whats the the cas, and afm?

 

maybe if your buddy would learn to use goddamn puncuation. i think thats what the hmmm was about, maybe not. and also learn to spell his own states name. sorry im an *******

 

well remember what was good THEN might not be perfect NOW. so pull out your voltmeter and double check the TPS, make sure your 5th and 6th ports are opening. Check to make sure your intake pipe is on securely. Check plugs and see is the spark-plug wires are within specs( with the right resistance).

take a break for a while and tackle this this weekend. Sometime all you need is a little of time away from the project to realize where you may have made a mistake.

 

this happened to me on my n/a... i pulled off the throttle body when it was running perfectly... put er back together and it wouldnt idle properly.... it would also die like u said... u might want to reset ur tps and the idle adjust screw. i hope that kinda helps

 

the CAS is the Crank angle sensor ( test it to make sure it's within specs otherwise it must be replaced) the AFM is the Air Flow Meter ( goes at the end of the intake pipe and has the filter at the end)

no, I'm an *******, you're the wet, heavy, fart that comes out of the *******. go to the lounge is you wanna post-*****.

 

true thank you mabe i doo need a break from it for a while , and ill check every thing , i apreciat the help and i miss spelled the state on purpose ya know to be funny and punctuation just ain't all that important to me righ now fixing my car is please i just need good feed back to fix my problem not smart *** coments, again thank you for your time and help Phoenix any serious and helpful advice that any one can come up with just pm me thank you .

 

DO NOT MESS WITH THE IDLE SCREW UNLESS YOU ABSOLUTELY KNOW HOW TO SET IT TO SPECS.

Please clear this up for me:

are you running on the HEADER only? you need the split-air-pipe to open your 5th and 6th ports ( maybe that, along with TPS are giving you bad high end?)

 

thank you guys that is some good points to tackle i ll dig out the volt meter and start double checking every thing tomorrow, thank you guys for your help if all this checks out fine ill be back again for more help .

 

i still have the manafold hooked up just the rest of the exaust isnt hooked up

 

the split air pipe is hooked up though

 

well call it a day and tackle some of these things tomorrow.

 

im not so much post whoring as i am giving helpful info on other points. like how alot of people on here wont even attempt to read that god awful blob of words you formed on your first post. i got done with about 3 what should have been sentences and quit reading when i realised it was 1 giant run-on. it helps alot of this forums to not use internet form of words like wut and numbers and letters in place of full words. not that you did that but that along with giant run-ons get on my nerves. sorry if you dont find this helpful...

 

Hey Mr. Proper English, how about capitalizing some of your words. People may understand you better. I do agree about the hugmonguous run-ons, they're hard to sipher what's said, but no need for 5 comments and it. Anyway, sorry about your car, I wish I could help, but i haven't had that problem yet. Emphasis on yet. *sarcasm* I love rx7s. -_-

 

well you made it number six, and my pointing that out makes it go to seven posts. So how much did you help?

and by the way, even when shortened its not sipher.

 

shesh! Sorry about my inproper english, dang! I was just looking for help on my car problems not an english lesson. Thank you though for your unsolicited advice on my inproper english. If you didnt understant what I wrote just ask. That would be the conciderate thing to do. Not bash the person. Anyway back to the issue at hand, not the english lesson. I'm going to check on these tomorrow. If all the things that I have been advised to check are good then I'll be back for more help. I do however apreciate any help with MY CAR PROBLEMS and your time.

 

Ok guys and gals I need some pro. advice, something fearce. And before I get started I already checked the FAQ and it didn't help one bit. Now here is the situation. I have 2 rx-7's, an 86 na and a 87 na. My 86 na has a streight body, good ac and heat. Everything works on it except I lost one of the apex seals on the rear roater, a busted drive shaft and the tranny was slipping bad. So to save money I did what any normal RX-7 lover would do. I took my bad drive train out of my 86 na and took the good drive train out of my 87 na and put it in my 86 na. I only did this because the body, ac and heat was shot in my 87 na. It had been wrecked but the drive train was fine, no problems. Now here is were I need the help. See it wont stay started now. I give it gas and it will kill it most of the time and it don't have any power. It won't get over 60mph and it heasitates and sputters like its not getting enough fuel. I double checked all my grounds and even added a couple more to be safe. I double checked my fuel lines with hanes and this web site. It has a brand new TPS, a new battery, new injecters, new fuelpump, new fuel presure regulator, new altinator, ( I had a k&n ram air filter kit on it but I took it off thinking mabe it was messing with my fuel air ratio and put the factory air breather on.) It has a new mass air flow sensor, new hoses and I just replaced the rear seal in the tranny, the o-rings on the oil filter tower assy. and new oilpan gasket. I have hooked every thing back up just the way it was. I even put in the ECU and CPU from the 87 na in the 86 na and it didn't help. So I just switched them back. I even cleared the codes by removing the negative battery termanal and holding the brake for 60 sec. Nothing is working and I am at a loss. Why won't it run like it did before when it was in the 87 na? What am I doing wrong??? Please help!!!!!!!!!!!!!!!!!!!!!!!! [/QUOTE]


(Hopefuly now you can read and understand this now enough to help. Thank you all again for your time and help.)
