My car will not start when it is cold or warm unless i depress the gas pedal. After that it idles perfect. In neutral when i rev it the engine seems to have power and doesn't misfire at all sounds completely normal. When i go to drive it the car seems like it is starting in 2nd or 3rd even though i know i am in first and the acceleration is nowhere near what it should be.
I've tried cleaning the maf with maf cleaner, spraying around w/ carb cleaner for vacuum leaks found none, unplugging and messing around w/ vacuum lines, the timing is right on checked w/ timing light.
The computer gives me code 55 which means normal in mode 3 and in mode 2 it is constantly in open loop mode and never in closed loop mode so i suspect something do with fuel but i am not sure what.
What could be the problem, fuel pressure? but why would it sound so good in neutral and it eventually gets up to speed just slowly, does the tps affect the amount of gas the injectors squirt maybe they arent squirting enough. The spark plugs look a little lean but nothing too bad.
anything else i should check? thanks.
