An engine vacuum leak from the  intake manifold gasket may cause the engine to misfire or have a rough idle which may also illuminating the Check Engine Light.

Welds on the catalytic converter heat shield can corrode causing a rattle during acceleration and possibly causing Check Engine Light illumination. The common repair for this issue is replacement of the damaged catalytic converter.

Failure of the ignition power transistor can cause a "crank-no start" condition.

The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.

The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.

Crankshaft and camshaft position sensors can leak oil into the connector causing Check Engine Light illumination. The engine may also stall as a result. Leaking sensors should be replaced.

Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.
