| WHEN I START MY 08 GMC SIERRA, IT SOUNDS LIKE IT CONTINUES TO FIRE. WHILE THIS IS GOING ON, THE MOTOR ALMOST SOUNDS LIKE IT IS "HALF WAY" RUNNING. ONCE THE MOTOR FIRES UP AND RUNS RIGHT YOU CAN SMELL A RICH GAS SMELL. THIS ALL STARTED AFTER I TOOK IT TO THE DEALER WITH A SERVICE ENGINE SOON LIGHT. THE DEALER ADVISED, THE LIGHT CAME ON WHEN I SWITCHED FROM REGULAR GAS TO FLEX FUEL. THE DEALER "REBOOTED" THE COMPUTER AND PREFORMED INJECTION CLEANER. NOW SERVICE ENGINE SOON LIGHT IS OFF BUT I HAVE THIS STARTING PROBLEM. THEY HAVE HAD MY TRUCK FOR A WEEK AND STILL NO WORD. ANY IDEAS? | |

I have less than 1,700 miles on my new '09 Silverado 1500 (4.8L), and it's starting to give me a fairly rough/jumpy idle when I give it a cold start. I live in Texas so the engine's not *literally* cold by any means. (Highs nearly 110 F this week) I don't actually have trouble starting it, and the idle does smooth out within 30 seconds or so. It just sounds different than when I first got it, so I'm wondering if this is anything I should be concerned about. Have to admit it does have a better growl to it when first started now, but I'm guessing that's more to do with the muffler breaking in.

This should be simple, but I'm having problems removing the spark plug wires/boots from my 2004 5.3L Silverado. Any techniques??

Replying to: obyone (Aug 03, 2009 4:06 am) Thanks! I already bought a pair from Sears that look only slightly different. I'm trying not to damage the wires, but they don't seem to want to budge. I'll keep trying.
