It's been a long time since I've been here. But these problems are bugging me and I figured I can't be the only one. If anyone can help I really would appreciate it. Every time I'm at a light the car is shaking like crazy. RPM's jumping up and down. Not too much but enough to shake the motor. CEL on went to get it scanned and got this
coil 5 bad. o2 sensor bank 1 error or whatever and cat. converter bank 1
so I changed coil's 4,5, and 6. all new plugs and changed both 02 sensors in bank 1. no cat. conv. yet. $$$$
Get in the car and bam same thing. Now I cleaned the MAF. Cleaned the TB. and still same thing. Any suggestions?

What kind of miles on it?

Have you read all the threads about motors melting-down due to converters plugging?

never heard of that. The car has 70,000 miles. It was rebuilt under warranty at about 25,000. The infamous PCV no oil deal.
