I wasn't able to look at the o2 sensors unfortunately. I suppose it could be the intake tube somehow, but, i can't figure out how. everying is tight. no leaks. could it be that water got thru the maf and into the intake? if so, then what? Could water have killed my MAF sensor? I'm going to take the compressor off i think next week to replace the fuel injectors. I'll have my mechanic look it over to make sure i didn't miss anything. Hope I make it to work tomorrow.

Just a side note. the carwash i got had "undercoat" treatment. the water pressure was enough to unplug the weather pack that hooks up the truck's horn. I noticed that as soon as I got home.

Try some fuel treatment for water removal.

Try taking off all your intake tubes and put them back on just to make sure. You may see something else while your doing that.

It just happened again. I hooked up the Predator, the O2 sensors said, 750,0,500,250. I also noticed that the boost gauge was sitting on 0 at idle. usually at idle its on -25ish. Does that spell vacuum leak?

How does the whipple bypass system work? Is there any way the bypass system could be not functioning properly?

If it's stumbling ... the vacuum gauge is going to go towards the center. This is an odd one to say the least.

Was it on E when you went to fill up?

Does the truck go into reduced engine power mode? sounds like a code my truck was throwing when I first put my blower in. I will do a search on an old thread of mine, the problem was fixed by one of the members here modifying one of my air/fuel tables, I believe.

Are you sure you aren't thinking of a P0101 error ?

Had the exact same problem with my last vehicle, a 96 Whippled 454 Suburban. Happened every time I went through one of those car washes with the damn upshoot when you drive in. I think water gets drawn into the air intake system somehow.

The only thing that seemed to fix it for me was putting in gas line antifreeze. It was one of the reasons I got rid of the vehicle though....sorry to hear you are having the same issue.

Good Luck!

so you have no vacuum?? i should be around -21, it almost sounds like the bypass valve on the whipple to me or a leak. you should have vacuum
