Report A Problem

2005 Monte Carlo shifting extremely hard on initial takeoff from a complete stop. About every 3-4 weeks car jerks violently forward. Once out of first gear, the car runs smoothly. Took the car to a Chevy dealership who was able to duplicate the issue and confirmed problem with the valve body. Valves, gaskets and selenoid replaced at a whopping $1400. No other major mechanical issues with the vehicle, I'm the original owner and car is main...

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

The exhaust gas recirculation (EGR) tube which connects the EGR valve to the intake manifold may develop an engine vacuum leak, causing the Check Engine Light to illuminate with code P0171 and/or P0174 stored.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.

The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

 

Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.

The fuel pump may fail causing engine to stall and not restart.

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault.

The water pump may develop a coolant leak resulting in an engine overheating condition.

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.

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