Still have rough idle and chirping noise. List of repairs in last 3 months 4 strut mounts,2 sruts front,1 wheel bearing assy. drivers side, tie rod ends, bushing kits all around, fuel pump, little black box by filler cap? coils, ICM
maf, idle control valve, throttle pos sens, plugs and wires twice, fuel filter,
pcv valve, intake gasket, plenum gasket, cleaned and back flushed fuel injectors, water pump, serpentine belt and full tensioner, cat and o2 senors
all new motor mounts which did fix shifting problem, top motor mount struts,
and last but not least air pump was froze up. guess what its new now. almost forgot the new EGR valve. Heres the thing this rough idle is killing me I could have bought a new Camero by now. OK this little sucker gets up and goes now and doesn't hesitate or miss when I'm the gas or driving normal. I hear this chirping noise up by the new air pump like an exhaust leak coming out the air pump like EGR is stuck open but its not. and at stop sings it just chugs idle up and down 300-500 rpm a little better in park and neutral.


Please Help I'm out of $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
cam sensor?
crank sensor?
elec short?
I did check all relays none were stuck.


At this point its me or the car and I will beat this poor excuse for a Chevrolet!

 

FYI - Moved thread from MCF Problems section to Monte Carlo Repair Help.

 

Is the car throwing any CEL codes? Also, do you have a scan tool that can check misfire data from the PCM? Perhaps you have an issue with a bad injector for example....
