Fireman31 Posted November 24, 2008 Report Share Posted November 24, 2008 Seems like it is time to run some logs ASAP, being lean on both sides of the motor is no bueno. I assume you are seeing these codes under WOT? I would avoid going WOT until you figure out exactly what is happening........ Quote Link to comment Share on other sites More sharing options...

I cleared the codes... would they come back on if it was still running lean??? What should my AFR be running around 10 lbs of boost with a vortech s/c?

toolhaulerSS Posted December 16, 2008 Report Share Posted December 16, 2008 HAZMAT - did you ever find out what happend or set off the codes again ? I had this happen today on my 4.8 work truck. drove to work in the moring with a -7 * temp and was fine. went out to breakfast 3 hours later and didn't notice a engine light. I saw the engine light on about a hour later on my way home, stop at checkers for a scan and these codes came up. I cleared them and drove home with out it coming back on. mostly a stock truck but have a tune ,new fuel fiter, new MAFS, plugs wires , new cats , new cat back, new trans and cai . I'm thinking maybe some small fuel frezze up and with the tune it tripped ??? is there any thing I should look at or check out. I going to park in the garage tonight it's going down to -15* , I love working out side. Quote Link to comment Share on other sites More sharing options...
TheGunny Posted December 16, 2008 Author Report Share Posted December 16, 2008 I had them come up twice within a two month period, both times i just cleared them, I have not had a problem since, i was thinking that air temp may have had something to do with it, my trucked was tuned in socal at 85degrees and i just brought it to portland where its 12degress right now... I just monitor my AFR and as long as that looks good I think I'm ok... Quote Link to comment Share on other sites More sharing options...
