help! running rough and engine shake

lazyworm · 11-05-2009, 10:12 PM

i feel my mustang runs very "rough" compare to what it used to be. the engine is getting bit louder and the car accelerates slower for some reason. the car still idle around 700 rpm but the engine vibrate during idle. these problems are amplified when driving w/ AC on.

My car is a 02 3.8L manual Mustang w/ 65000 miles

Thanks!!

when the last time you gave your car a tune up?
also have you checked your vacuum lines? what do they look like?
