when i start the car after its been warmed up for the day, the idle will bounce up and down a few times before correcting itself. i believe everything is tip top and ive been using injector cleaner just to see if it helps. do anyone know whats it is?? thanks

 

vac leaks, bad O2 sensors, ECT sensor or EGR.

 

o2s are new, egr is not very old, whats the ect?

 

engine coolant temp.


check for vac leaks
