I have a 94 delta 88 royale oldsmobile and i've been having a problem. aside from my catalytic converter getting red hot and smoking, my car shakes at speeds id say anywhere over 37 mph. when i keep constant acceleration for a few seconds, the front end starts shaking. when i take my foot off the gas, it goes away, when i put more gas on, it goes away. i dont feel the shaking coming from the steering wheel or either side of the car. when i turn while it is shaking, it stays, so i thought it couldnt be the cv joints. ive changed the plugs recently and cleaned the wires, oil and trans fluid are great. trans is only a few years old. i ran a diagnostics tester and i got no codes. i know hot converters can be caused by rich mixtures and the diagnostics tool flashed between lean and rich but never stayed on either. i checked the MAF and O2 sensor computer connectors and they looked fine. i am guessing it could be the front oxygen sensor gone bad itself, but could this cause the shaking? what about fuel injectors? any help would be awesome! thanks a lot!
