If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
A Lack of power, poor fuel economy, and black smoke from the exhaust can be caused by a defective MAP (manifold absolute pressure) sensor.
Worn motor mounts can cause the motor to rise during acceleration, causing a clunking noise and possibly damaging the AC hoses. Damage to the AC hoses can cause a loss refrigerant resulting in no cold air from the AC. The motor mount will need to be replaced prior to repairing the damaged hose or the problem will continue.
While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
Bad motor mounts can cause the motor to move excessively, which pulls on the MAP sensor vacumn hose every time you step on the gas pedal. This either weakens the hose so it collapses (causing low vacuum flow) or pulls the vacuum hose that connects the intake manifold to the MAP sensor completely off of the sensor. When the hose is disconnected from the MAP sensor, a full rich condition will result.
