Runs like death......
I have a s10 with a ls1 in it that I built a while back, I put a cam in it, and had a mail order tune to that cam, but the truck always ran really rich. If i park it on the driveway and let it idle the exhaust will leave to big black soot marks on the driveway (turndowns). This year I started it up again took it for a drive and it was way down on power, felt like it was loading up. Had to keep it it above 3k to drive it home. I parked it and let it idle, barley running, Its puffing black smoke out the exhaust like a diesel. My question is what would make it run crazy rich like this after just sitting over the winter? Also are there any good places in ct where i can get this thing tuned?
