just rebuilt the motor, ka24e. the car starts but is running rough. checked and set timing and idle at 650 with TPS out, when the TPS is plugged back in the car will shake start and then die as if it idles too low? took out the IACV and cleaned it with carb cleaner and all that. Another big problem is the car seems to be running rich and will not rev past 2500?? could this be due to too rich of a mixture? it's almost as if it has a rev limiter at 2500. Already replaced the o2 sensor, maybe a bad MAFS? bad IACV? any suggestions as to why it wont hold idle with the TPS or why it wont rev past 2500? All help is appreciated, thanks guys!
