ok so driving in town as normal, the car started to sputter.. next thing i know, the idle wants to die, and it wont rev up. It bounces when u floor it at like 2k rpm, but if u give it gas really fast, it will finally rev up.. but the idle still wants to die. Im thinking fuel?? I changed fuel filter, bypassed fuel ecu, no change. I have a spare fuel pump, im changing that now. I have no idea. Maybe crank angle sensor?

 

map sensor.

 

bad map sensor will do that trying to get a greddy map to work on a mines ecu will let you know the results.

 

i agree with map sensor i had the same problem, except i didnt even have a freakin map sensor lol..
