[gunit]

wow guys i have been paying close attention to this conversation mainly because i came to post the same problem. Might i add i have been having it for quite awhile and the exhaust thing is really an issue since in notice a nasty lil sag right at the x pipe. However my motor races or dies there is no rhyme or reason for it no particular time hot or cold it driving me crazy. Has any one bounced around the idea that this could be a grounding issue electrical not vacuum cause if you have a leakage issue you will have it all the time but electrical problems will throw you fits. you might want to do the improve grounding thing in the above post and then see where you are...whew that was long winded i apologize
