Engine not running correctly when warm

Good morning,

I would first replace the plugs as it could be that easy.

Beyond that, it could be low fuel pressure.

Do you have any codes stored in the system? P0300 is common for this and I attached the flow chart for it.

Roy

Will bad spark plugs make your car get no power at all when you press the gas pedal?

No, it would not. Bad plugs would cause it to stutter but not prevent acceleration.

Low fuel pressure would cause this.

Are there any codes stored?

Roy

P1779,P1780,P1795,P2176,P0122,P0222,P0056,P0161,P0700,P1779.Those are the codes I got.

Those are the codes I got.

Okay.

1779 is a serial data line failure. The transmission cannot communicate with the rest of the modules.

1780 is a code again for communication for shift feel.

1795. This could be set from a dirty throttle body. Clean the throttle body.

2176. Related to the throttle body cleaning.

122. This is for the TPS on the throttle body and related to the cleaning as well.

161and 56. This is for heated O2 sensors.

700. This is a general code for the transmission. The beginning codes are the codes needed to be checked.

Roy

Yes, they are.

You are going to need some help on this one.

You need a shop that can check these for you to see why these codes are set.

Roy

Okay, thanks.

You are welcome.

Always glad to help.
