I'm gunna get the valves adjusted, can you guys show me the link for the best thread on this, I would like to show the shop I'm going to go to.

The metal shield between battery and headers is still in place, if thats what you guys keep refering to. At first I was thinking about a battery "blanket" that may have come on the stock battery which I cant remember.

Any updates to this? I'm having the same issues, but only after I supercharged my car. I'm thinking it might be the tune. I will need to contact my tuner to see what he thinks.

I had this same issue and it ended up being the battery. Car would sit all weekend and start fine on Monday, Stop and get gas then have trouble starting and kinda stumbled, with a low rough idle then even out. After several months it started having the same problem cold. Replaced the battery and all was well.

Would the battery brand matter? I actually just put a new battery in during my tuning session, so that is one more factor to try to rule out.

Maybe, when you pulled the old battery --- then added the new battery ---- the clearing & re-learning of ECU memory is what "fixed" the problems?
