Known Problems

If the engine surges while being driven in the forward gears, the intake tube between the mass airflow sensor and throttle body may be split. The damaged intake ducting will need to be replaced.

A dirty, or contaminated mass airflow (MAF) sensor can cause the engine to run poorly. There may be a Check Engine Light with trouble codes relating to the MAF sensor, P0102 and/or P0103. In some cases, carefully cleaning the sensor element will fix the problem, but replacement may be required.

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. If you do not hear the pump the inertia switch should be reset, it will "click" when it is reset.

Some models may have a problem with stalling under light acceleration. Updated software for the powertrain control module (PCM) is available which may help with this concern.

The engine may develop a crank no start condition due to a faulty ignition switch. The ignition switch will require replacement to correct this concern.

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

If the engine stalls when coming to a stop, check the automatic transmission fluid (ATF) level. Low ATF fluid level can cause the torque converter lock-up to stay on, stalling the engine.

Excessive engine vibration or knocking noises heard while the engine is idling, being started or switched off are usually caused by a defective engine mount at the top right side of the engine. A redesigned engine mount is available to alleviate this problem.

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

The intake manifold gasket can fail causing vacuum a leak and/or a rough idle condition. Replacement of the leaking gasket will be necessary to correct this concern.

The oil seals on the supercharger can fail and cause excessive oil consumption and bluish gray smoke from the tail pipe. Supercharger replacement is commonly required to correct this concern, this can also be an expensive repair.

The "Bypass Air Control Valve" can fail causing a low engine idle and possibly stalling.
A knocking sound heard from the front or rear suspension while driving over rough roads may be caused by the sway bar linkages. The linkages should be inspected for tightness and condition; there are redesigned linkages if replacement is necessary.
