I know its not the ecu because i ve used 3 diffrent ones and all the same. in order to keep it from doing it. i have to shut the car off. count the 3. turn it back on and keep on going. and it clears out. Engine codes are showing. but all just sensors. the car randomly does this to where at 3k it sounds like its hitting the rev limiter. plus i dont know if this has anything to do with it. one more thing. do vtec pinouts exsist in a 92 dx hatchback dash harness?
