Repairpal verified Pontiac Firebird problems
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
Failure of the rear transmission mounts is common.
The head light door actuators may fail causing the head lights to become stuck in the raised or lowered position.
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 tail or brake lights may be dim due to a poor ground connection inside the light socket. Failed light sockets will require replacement.
The transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.
The fuel injectors may short out electricity causing a rougher than normal idle.
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
The hood and rear hatch supports may fail causing the hood or hatch fall back down after being raised to the open position. Replacement of failed supports is recommended.
