O.k here's my problem! I originally took my truck to the shop to have some one off turbo headers made cause the ones i had were cracking at all the welds and had already been repaired before. That was the only problem prior to going in and 5 months later when i got my truck back my abs light is on, im leaking oil from where the oil dip stick tube goes into the oil pan, my check engine light is on saying i have an evaporator leak and when it comes on my engine is idleing around 500rpms none of which was happening prior to going in. If I clear my check engine light the truck idle's perfect for 70 miles or so then the check engine light comes back on and it starts idleing rough again. It has no affect on my engine performance though when you accelerate only when stopped! I guess my question is ... is if the check engine light is coming on cause of a small and large evaporator leak being detected wouldnt it still idle rough even though i reset the computer.
