The high pressure power steering hose will commonly leak fluid; it should be replaced.
The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
The PCV vacuum hose under the upper intake plenum may become brittle and crack causing an engine vacuum leak.
The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
One or more of the fuel injectors may short out electrically causing a rough idle condition.

The serpentine belt tensioner can fail; it may become noisy and/or the belt may jump off. Replacement of the failed tensioner will be necessary.
The EGR valve has been replaced, that didn't change the problem. The car will barely start, you have to give it a lot of gas to get it on, and to keep it from cutting off. When I have driven it, when I went a littler faster, it would smooth out, but when I wasn't going over 60 it would shake and sputter a lot. Any suggestions?
