PCM SENT TO CALI/RETURNED/SAME PROBLEMS I've been w/out my car for almost 2 weeks. Dealer called me today and said cars ready. PCM was reprogrammed and it is running great. Take it for a ride on the interstate, let it sit at idle in park and it still idles like sh---t and shakes as well. Heard a little pinging at high RPM'S, but not as much as before. Don't know what to do from here. Any suggestions?

 

1 clogged cat
2 bad coils / plugs
3 carbon stickin up secondarys
4 warped intake manifold
5 bad fuel pump or fuel pump wiring harness.
6 broken motor mounts

Well at least you know its not a problem with the PCM

 

I second swoopes list!
I would put motor mounts up higher on the list, but he seems to cover it!

 

turn the stereo up and chill ...
