2001 GMC Yukon Denali 6.0L Poor Idle Quality, Surge, MIL Lamp on VIN: 1GKEK63U41
When I sprayed the rear of the intake on the drivers side the fuel trims came up and the o2s went up. Changed intake gaskets and everything works great. Thanks to all! Trouble codes: P0171, P0174.

2002 Pontiac Grand Am SE 2.2L security system VIN: 1G2NE52F42
This Grand Am has not acted up since it came in so the customer doesn't want to go any further with it. I will keep all the replies in mind for the next one.
