Any Ideas on what this might be?
I did my heads/cam install and had someone do my tc and cooler. After my tuning, the car is running great, idling perfect with the cam. The only issue I have is just a nagging one. When I start the car let it warm up, then pull off, there are a few seconds where the car acts like it is getting no spark, bogs, rpm's drop. It lasts about 15 seconds, clears up, and throws no codes. It runs perfect after that. It seems to happen at almost every start up.
I have to think air pump/egr are the culprit, but haven't found it yet. Any ideas on what it might be or troubleshooting?
Thanks a lot....
