just unplug a sparkplug wire and drive it around some..this should set the light off

 

Thanks guys...I am thinkin this would be my best bet and least damaging in light of my lack of mechanical knowledge LOL...my luck I'd cut a wire that holds everything together LOL

 

Just put Diesel fuel in your gas tank. You should find out REAL quick if your check engine light works......

 

easiest way to see if your check engine light works is to not put the gas cap back on. You'll get the light for that too. I've had that happen a few times to me already.

 

WHOOOOOAAAA - i wasn't serious when i said cut wires under the hood (but the belt comment was semi-serious). now i'm gonna lose sleep thinking that somewhere, there's a disabled hummer because of my advice . . . .[]

 

yep that will work too and filling up w/ gas w/ the motor running will do it to

 

don't think filling up with the motor running will trip the light if the cap is put back on tight. I have never shut the motor off while getting gas and as long as the cap is put back on tight the light never comes on. Theres a vacumn sensor or something in the system for the cap.

 

The system only checks this gasoline vapor emission system after you have driven 20 minutes or longer and then only after youturn the key off and stays off for 10 minutes or more..Only then will it store a code and indicate on the next start up (SES) and will correct itself if the cap is placed on properly during or before the next full cycle as stated

 

I duuno, maybe like the TPS system mine is messed up. All I know is that if I get gas and don't put the cap on tight my light will turn on in less than 2 miles....every damn time. It's like clockwork.

 

Hmmm..Interesting..yours does have some out of the ordinary chit going on..for example the terrible gas mileage, but runs faster than any other stock H3 on the road...That one really blows my mechanical mind.[&:]
