i have a 95 eg coupe ex model with a usdm B16.
the car sputters really bad when I press the gas! If i gradually press the gas it wont do it as bad, but if i try yo get on it or down shift to pass other cars it sputters really bad. Ive replaced TPS sensor, Map sensor and complete throttle body!! car still does the same thing. I have a p28 on the car. the ECU still throws the same codes, which r TPS and MAP but only when i hold the rpm at a high range, about 6000 or above. When i connect a p72 it only throws a code for the fuel pressure system. i have a walbro 255lph fuel pump and adjustable regulator. my fuel pressure is good and doesnt drop. PLEASE HELP!!!!

 

If its throwing those two codes have you checked to see if you switched the plugs around...I believe they are the same round head style plugs...

 

ya try switching your tps and map sensor plugs...

 

tried that. proble only gets worse! the check engine light wont come on unless I hold the throttle @ about 6k or higher for a lenght of 10-15 sec. then it throws the codes. other than that no check engine light. car runs perfect when engine is cool, but once it reaches normal temps it starts sputtering like crazy. please help any advise will help

 

problem solved!!! now having V-tec problems. when the car is cold it hits great, but once it warms up to normal temp it doesnt work nore does it throw any codes! WTF???? please help any advise will help.

 

what ecu are u using right now? also what was the previous problem
