Long drives and engine codes....

[Ldub]

I had 5-7 CEL's after every gas stop, same deal, different codes (1137,1157,1171...I think, going from memory. ) read, clear, read, clear, clear, clear, clear.
After she got used to the new gas the CEL's would stop & everything would be fine until the next gas stop. Pretty sure it's altitude related, though there could be some filter oil residue on my MAF sensors that would be a contributing factor.

If at altitude my VX will throw a code if I get on the gas to pass or just pick up the speed quickly. I think not enough oxygen tricks the sensors and throws the code. My CE light will usually go out after a few days, if not I just disconnect the battery and reset it.

Mine does this too. Anytime I clear the code it comes back on within a day - usually. I went 3 months with it off until the last Moab trip - it has been on ever since. I already know it will go off again within a month, but I don't know what code it throws.

My Check Engine Light came on this evening, and twice I popped the hood looking for problems. I can't find any! Even the air filter looks clean! The only fluids consumed are the winshild wash fluid and fuel. No oil usage here.
No performance problem that I can notice, but I don't no what sensor could be the problem?????? Huh????
I guess I will pull the battery for 15min and see if it resets itself.

a word of caution, but dont know how reliable it is,
i was told that because of my code 1171, lean on acceleration, the computer was dumping too much fuel into the engine, and that that fuel was combusting in the cat converter, and in a matter of days destroyed my cat. converter..........

bulldoggie, get the code read before you pull that battery, if its not too late.

No Isuzu dealer nearby, I think someone said Autozone will read them?
Do they charge a fee for reading codes? Will NAPA read them?

[IndianaVX]

no charge at auto zone, or napa, or similar.....just write down the code they read, then look it up here using the search
