Problem Reports

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.

A ticking sound (lasting only two to three seconds) may be heard when starting a cold engine. Worn swivel pads on the exhaust rocker arms are commonly the cause. Worn swivel pads will require replacement.

An loose alternator drive belt may cause a growling noise in the engine area at low speeds (usually when accelerating from a stop). This is often mistaken for catalytic converter failure.

When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.

Door weatherstrips mounted on the body tend to shrink with age, leaving gaps that can create wind noise or allow water to leak into the car. Our technicians suggest the door weatherstrips should be replaced to correct these issues.

The instrument cluster may illuminate randomly to its full brightness and/or the fuel gauge may drop to the empty position. Typically the symptoms are infrequent and the instrument cluster returns to normal operation after a few seconds. An update to the body control module (BCM) will fix this problem.
