1990 Oldsmobile 88 Problems

Car Won't Start and Security Light is On

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

Engine Oil Leak From Intake Manifold Gasket

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

Somebody ran into the front of my car and the bumper and headlights are done. How much do you think it would cost to get fixed and where can I find the parts?
Okay--I had an '87 88, but I have to review the car anyway, as it was my first. Strong engine, and absolutely a Detroit tank of a car, but it was comfortable as hell and low-maintenance. Problems: the headliner will sag on you as only GM headliners can. You will develop timing chain and valve problems over time.
