Report A Problem

The ignition module or crankshaft position sensor may fail causing the engine to die and not restart. Diagnoses will be necessary to determine if the module or crank sensor is causing the no start condition.

The steering rack may develop a fluid leak or fail causing the steering to become hard to turn.

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.

One or more of the fuel injectors may short out electrically causing a rough idle condition.

The PCV vacuum hose under the upper intake plenum may become brittle and crack causing an engine vacuum leak.

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.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians tell us this condition is best corrected by replacement of the front rotors and brake pads.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

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.

A dirty throttle body may cause a lower than normal engine idle resulting in a stalling condition. A stalling condition may also result if an idle learn procedure is not performed if the battery goes dead or is disconnected.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

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?

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.
