If there is a misunderstood set of codes for these cars, it is the infamous O2 sensor codes. Most of the codes possible are an indication that something else in the system is wrong (air leaks, fuel leaks, fuel pressure low, exhaust system leaks, etc.), and none of these issues are going to be fixed by replacing otherwise perfectly normal functioning O2 sensors. To do the right thing, you need to find out what specific code(s) the system is throwing, and then diagnose what they are telling you. More often than not, a new O2 sensor is not the answer.

As for the oil pressure light, I fully agree, stop driving the car until you know what the problem is; it may be a simple pressure sensor replacement, but continuing to drive it without knowing is flirting with disaster……….
