this started yesterday out of the blue, when the engine is cold the car runs fine when it gets hot it feels like theres random missfire or kinda jump/shake, when at idle you can feel the motor randomly miss/jump but when you put it in park it quits doing it, its only when the car is in gear and warmed up, any help would be appreciated, I replace the fuel filter and that did not change anything.

 

Watch fuel trims to see if it's an air leak.

 

I read the thread title and thought this was going to be a post about a hot date!

+1 on the air leak.

If it's neither air or fuel, then a faulty IAT (Intake Air temperature) sensor has been reported to give similar effects.
