OK, so I just purchased a 98, and the CEL has just came on, I had it checked and it was says its is the camshaft position sensor and an O2 sensor. Well on the drive home the oil pressure gauge was flicking back and forth from low to normal then stayed on low. It is making a winding sound and jerks jut a little going about 40 mph, I just bought this car and want to get it fixed, does anyone have any advice?
