First off thanks for looking.

Now on to the problem, sitting in the drive way it revs up with no problems but some back firing. as soon as i take it down the street right a round 4500 rpm to 5000 rpm it bogs down like to much fuel or some thing. as soon as i let off right back to normal. if i dont get on it hard no bog down at all but as soon as i step on it bogs down. if i go smoth past 5000 rpm i can get on it with no issues.

please help this is my first rx7 and i want to see what it's got lol

it is a 1993 r1

 

Hi there and welcome to the forum.

Start with the easy stuff - You could have bad plugs, bad spark plug wires, bad coil/coils.
Or perhaps a stuck secondary injectors thats dumping too much fuel.

 

Did you have the car checked out by a rotary mechanic or someone familiar with Rx-7s before you bought it?

I think you should take it to a rotary-specific shop if you don't know what you're doing.

 

are there any mods done to the car? also, what part of texas?

 

Those issues can be caused by an array of things. Have it checked out by a rotary shop.

 

killeen tx there is no rotory shops in my area and cant find any one to help lol. can you come up and help me out? i have all the tools

 

no i did not have it checked before i bought it. i didnt care i wanted the car if i had to put new motor in it. i got a super deal on the car. no rotory shops in area.

 

You're in for a world of hurt my friend. It's not as simple as putting in a new motor.

 

oh god...another impulse buyer that knows nothing about the car but had to have it. must have seen the fast & furious recently. lol

look man, this forum has a ton of info but you can't just hop in here and start demanding help without ever doing your homework.

use the search function. look for threads that cover similar problems/issues. try to self-diagnose the problem. what you describe could be caused by any number of things.

if you're not mechanically inclined / willing to do your homework, you need to find a rotary-specific shop or sell the car. simple answer.

 

Oh boy, put on your flame suit bud!

Seriously though, it could be ANY NUMBER of things. My vote is on leaky secondaries, only because I experienced the same exact symptoms a few years back. :P In fact mine were SO bad you could (and we did) literally unplug them, turn the key, and the car would start up...lol

But buying an FD as an impulse buy is a huge no-no. I did a solid 6 months of research before I bought mine, and still had to rebuild the motor a few months after buying (blown coolant seals).

 

Curious as well......Could be a number of things.....
Killen isnt that far from Dallas.

Steve Kan or Ari from RX7.com could help.
OP should do a search and do some reading.
This should be moved to South Subsection of the forum where the OP can get more help.

most people would be excited that some got an rx7 and help them out. yes i should do the home work and try to figure it out. but i thought that is what i am doing by asking for the help. is there a better site that helps me trouble shot the problem. i have built tons of motors nothing like this so i am asking for a little help if you dont want to help me then post on another post and let someone else help me i am just try to see if any one has had this same problem before thats it. just trying to find a good start point. sorry for upsettting you i bought a car.

 

You don't realize that we get at least one thread like this a week: People who are either looking to buy, or just bought, an Rx-7, who think that they're going to hop on the forum and have all their problems solved without doing one minute of homework.

"Homework" does not mean posting new threads. "Homework" means putting in time to research, read, research, read, and then when you can't find answers asking questions (in a relevant thread if possible, instead of starting a new one).

As usual, the person posting (this time, you):
#1 didn't research Rx-7s/rotary engines in general before you bought one
#2 didn't research the specific car before you bought it
#3 didn't take the specific car to an Rx-7/rotary knowledgeable person to inspect it before the purchase
#4 didn't read any of the information posted at the top of this forum (this thread, and this thread)
#5 didn't search though the existing discussions related to your problem by using the "search" link

Personally, (and I think may of the other "regulars" feel the same) I don't like helping people who don't try to help themselves. You didn't do any of the above mentioned things, and you would rather complain about the feedback you've gotten instead of following any of the suggestions, the easiest one being to use the search function. You're not the only one who's ever had this type of problem.

Then why didn't you SEARCH? You think in approx. 18 years you are the first and only person to have a problem with the seq-turbo system?

You don't even realize how typical this is. Search for "just bought" in the 3rd gen section and see how many threads come up exactly like yours.

 

The problem is that people who buy FDs as impulse buys give Rx7s a bad name. They usually lack the knowledge or drive to build the car the right way and end up telling everybody that the rotary isn't a good engine when in the end, they weren't good owners in the first place.

If you own a rotary, you can't be lazy and you certainly shouldn't clutter up the forums with useless threads. It's hard enough to search for a solution to a problem without people adding more threads like this to sort through that end up going no where. I know you might have an easier time in other forums asking for help but you probably won't get that here. Rotary guys give no quarter. These forums are a great resource so get used to using them. You will be highly rewarded if you do. Most importantly though, find a shop quick.

 

You are very close to the great folks at Rotary Performance (rx7.com) -- as the car seems to run okay I would drive it up there and let them thoroughly look it over at the very least. It would be a great starting point.

 

Make the trip to Rotary Performance and tell Chris or Ari that Ihor at IRP sent you. They are the best in the area.

A good starting point is the Factory Service Manual (FSM):

http://www.wrex-racing.com/web/fd/info.htm

Pull the ECU codes and see what shows up:

http://www.fd3s.net/engine_codes.html

Then use the FSM to troubleshoot anything reported. Since you don't really have a history of the car, you'll basically need to start from scratch.

 

thanks for the info i will try to contact them. thanks

 

thanks for the info. know one knows every thing they learn as they go just trying to learn thanks agian
