mine came on today and auto zone cant get it to bring up a code. so i took it to my friends garage and he cant pull a code either. anyone ever heard of a check engine light coming on for no damn reason? 03 tahoe 5.3 auto

were they not able to see any codes or was it just undefined? generic scanners can only do so much. if it's a manufacturer specific code (usually not important) then find someone with a techII

10/13/2005 2:50:45 PM

problem with the light then?

ok took it by the dealer cause a friend works there and he scanned it and it came up code 171 lean. i guess thats why it stumbled. so i am guessing its a fuel filter, and ill start there. but all day since this morn its been running great.

10/13/2005 5:06:21 PM

the code has to be more specific than that

ugh, what a turd. you've completely lost it. way to buy the worst diesel on the market i thought Tuite and i raised you better than that.

10/30/2005 2:45:40 PM

yall tried, the new dodges i have been driveing are not impressing me to much. so i went with something that i thought was the inbetween. damn if they would put a 12v in a new body style i would be on it.

10/30/2005 7:37:40 PM

what about a powerstroke? that'd be the inbetween.

10/30/2005 11:05:32 PM

shit. i have nothing but problems with my chevy and when it's time to buy a new one, i'll still buy another chevy, illbeit, a diesel at that. mainly cause of the allison, though.

when you reset it, does it come right back on and stay on? i've had a few fluke codes pop up now and then like that. they never come back when you reset it. sometimes it can be something as simple as an air bubble in the fuel line
