Thanks a lot guys. I was trying to time the engine at 10 degrees advance and set the idle since I failed California smog test. It passed the emissions part but when they checked the timing it was way off and failed it. They said it was 50 degrees advanced at idle which I find hard to believe since it has been running just fine. They reset it to where it shoud be but it ran so badly they had to abort the retest and driving home I couldn't drive faster than about 20 mph. Absolutely no power. I messed around with it for awhile and eventually took it to my mechanic who couldn't figure it out either. Timing chain was ok and I don't think the harmonic balancer was bad. When I set it to the original setting it runs like a champ but I won't be able to smog it like this. Any ideas. Is it possible the balancer is bad?
