Hey guys I have a question I've brought it to 3 different mechanics now and they cant seem to figure out the issue either.

So everytime I go from a stop and accelerate slowly the motor is almost sputtering with barely any acceleration but if you lay into it it accelerates no problem, also my check engine light used to come on but not stay on it would flash repeatedly and disappear afterwards.

Any help on this would be greatly appreciated I've also changed the spark plugs and coil packs so I'm officially stumped.

Thanks in advance,
Pat

 

Check for vacuum leaks.

Is it cable throttle or fly- by-wire?
