Replying to: pawngod (Jun 28, 2008 7:39 pm) i also want to remove the front bumper license plate holder as i dont need it in okla. Isn't the plate holder molded as part of the bumper? tranny seems funky Yeah GM hasn't gotten the programming right on the 6 sp auto. curious what that muffler looking thing is at the passenger rear tire If it's smaller than the muffler it's probably a resonator and will be removed if installing a catback which again doesn't do much except increase incab noise. |

I'm kinda curious as to how involved troubleshooting an "egr system failure" code on my truckis. As the truck is pushing 14 years old i figure this kinda stuff happens but i dont wanna tear into it completely blind. If anyone has any tips or ideas as to what the most common causes are, Lemme Know! i just put a new O2 sensor in a month ago so thats not it. The damn check engine light comes on and goes off sporadically so i figured it was just the gas cap leaking but the clown at O'reilly's says this is the problem, whatever. Any Help would be appreciated.

i have a 2003 sierra 1500 and i was wanting to do something with my exhaust, possibly 3 inch straight pipes. I live in saskatoon, and i was wondering where the best place would be to go to do something like that! I just cant stand not being able to hear my truck roar when i drive, its just too quiet.

This is a weird one .. hopefully someone can give me suggestions: Just recently (starting last month) .. when I park truck in garage (its shut off) ... after 10 minutes... I would hear a BANG noise - consistantly each evening .. I was not sure what it was .. so I stayed under truck each night .. and sure enough - after approx 10 minutes .. I would hear a single BANG - pretty loud. After monitoring this .. I notice the bang is coming from muffler. So I hear a single loud BANG after my truck(turned off) sits for 10 minutes. Any ideas ? The truck runs and sounds fine .. just a BANG after truck sits for 10 minutes .. this is consistant behavior. I am hoping someone has seen this before ? Truck is almost 6 years old - 25K miles - original exhaust. Thanks!
