1991 CRX DX, 100% stock D15B2, manual tranny.
New distributor (reman), cap, rotor.
No CEL/Code's.

Car ran fine then suddenly started sputtering under high load or bellow 3000rpm. Rev it up past that and it's like all power returns and it runs fine. But bellow 3000rpm it sputters real bad.

Just replaced the distributor (although remans often suck), cap, and rotor. Ran fine again for ten minutes (let it idle and warm up), then at full temp it started running like crap again.

I'm doing fuel filter, plugs, wires tomorrow. Any other ideas?
I've googled it, seen that it could be TPS, EGR (dx have EGR?), maybe 02 sensor (does it have 1 or 2?).

Thanks.

 

its the 02 sensor theres only one, this has been answered thousands of times at least 10 by me

 

un plug the 02 then drive it. if no change or worse. plug back in and reset ecu. Unplug the tps and drive no change or worse, reset, unplug map etc.... once you find it the factory base map limp home mode should run better. It is getto but it works for the most part.

 

sounds very similar to the problem im having with a sedan im working on

 

try this^^

 

Did you find a solution to this problem because my car is having the exact same problem.
