I just finished installing new valve cover gaskets and a new power steering pump, with all the needed teardown to do it. Now engine idles like crap, sounds like a fuel dragster. RPM's go up to 2 or 3000 and then down all by themselves. Finally homing in on a very stumbling idle of 500 to 1000. I put on a new TPS on the 75mm throttle body which had been working great. This helped a little, but still pretty bad idle. Exhaust also has a very strange smell, not sure it's a too rich smell, just very chemical odor. Above idle car runs great, smooth with lots of kick. Anyone have any suggestions --bigger T/B not good, bad IAC, catalytic converter failure, O2 sensor failure, what ???????
