codes

ok, so now this is starting to seem even more weird! last time the light came on it was right after i filled up. i got it cleared, no more problems. until i filled up again on my way back home. so could there be some sort of relation between filling up and this dumb light?!?! i know it sounds stupid... but who knows

Nope. It just tests how many rich lean transitions there are in a given time and turns on the light if there are not enough.

One of the diagnostic pointers on that code relates to poor quality fuel. Be sure you're only putting gas in your truck tier 1 fuel suppliers, no local mom and pop convenience stores.

i am. only 93 octane good stuff. im waiting for the rain and snow to go away and then ill wrap what i can if the exhaust.

Have You Tried E85

theres nowhere close by to get it

could the gas cap be causing this? the guy at the parts store thought it could, so before i spent $50 on exhaust wrap i spent $5 on a new cap

Nope. The gas cap has nothing to do with the O2 sensor switching ability.

thats what i thought. but im trying to get a job from this guy, so i didnt want to say no. lol

So now I've tried wrapping the headers, everything seemed to be going good until i was driving down the highway and what do you know, it came back on!!!
Does anyone have any more suggestions? Or should i just go and get someone to hook up their fancy schmancy computer and see what they have to say?

Were the codes cleared or was the light just off? Maybe you need the codes cleared and go from there.

They were cleared, i wrapped the headers, then it came back up just a little bit ago. And i haven't gotten a chance to clear them again.

How are you clearing them?

with the scanner type deal at advance auto

Hmmm.....:ugh2:

is that a bad thing?

Don't know....it's another variable.

So is there something else I should be doing instead??
