having trouble with my 88 rx7 conv. The car will start idle between 1g down to 200 then cut off. You have to stay on the clutch to drive it, and the car has no power, when you come off, it just shuts off! I replace the exhaust: Magnaflow catback, replaced the fuel pump: racing tecq 255, replaced the plugs and wires, replaced the mass air flow sensor, replaced the 0-2 sensor, replaced the stock intake with a honeycomb filter, replaced the oil cooler. Should i replace the pressure sensor!? My friend said there could be air in the fuel line or the timming is off. Im just lost!

 

you took the stock exhaust off,Correct?..so you wil have to Set the idle again to Compensate for the Free flow,rather than the Hindering of the catalytic...Also,I am wondering why you have a 255 Lph Pump on the car...do you have an SAFC or anything on the car?

 

No I Dont Have Safc. Im Tryna Get The Car Prepped For The Engine Swap At Tax Time! Still Want To Drive It Now Though.

 

I BROUGHT THE FUEL PUMP THINKING MAYBE THE OLD ONE WAS BAD, BUT I HAVE NOT DONE ANY TUNNING!

 

I suspect it may be your TPS is going, it's a common problem with FC's these days.
Post over in the Richmond thread https://www.rx7club.com/showthread.p...43677&page=207 somone may have an extra one or at least help you test it out

 

DAMMIT Dave! You beat me to it! Lol... I'd say the TPS as well... Where in Richmond are you? I may be able to help you out this weekend if you're close. I'm in the Chesterfield area.

 

Well you look at second gen forum and I see at least a dozen TPS threads pop up every week with the same symptoms.

At least he doesn't have our overheating problem.....yet.

Just Brought A Tps, Will Try It Friday!

 

Make sure there isn't an unplugged, misplaced, or cracked vacuum line.

 

not to be a bad news bear but it sounds like you have a blown rotor. If it's down on power and you can't let the clutch out without it stalling it is probably done.
