Well, I put the old COPs back on and the problem was still there.

Am I down to vacuum leak or Fuel injectors?

Clogged cats?

 

Thanks. How would I check those?

 

I think I'm just going to take it into the dealership. The price for diagnostics is $95.00 and my mother in law gave me a crispy new $100.00 bill in my Easter basket! I'll get the diagnostic and do the repairs myself.

Thanks to those that offered some help.

 

Diagnosis came back as clogged catalytic converters. I asked the tech which ones and he said the two rears as the front two are called resonators. I don't have the $$$ for cats righ now, but I do have the $$$ to cut them out and do the "how to trick that pesky o2 sensor" trick--

I will get on the cutouts tomorrow and let you all know how it worked out. I'm still not sure how that would throw a lean code in bank 2, but at least its something that might work!!!

BTW, I'm over mileage for the emmissions warranty.

 

Try cleaning your battery connections. I had a very similar problem and it was just a poor connection at the battery.

 

I would suspect your lean condition is being caused by your Gotts mod and your edge. I believe the 04-05 5.4 engines were borderlined lean from factory. Your homemade cai just made it worse. You need custom tunes to support the cai.

 

I just have to laugh.

So I had the cats cut out on my lunch break. It feels better, but I have not really had a chance to give it a good run through. I can guarantee that I can not hear the pinging anymore.

Why you ask?

Because without cats, the truck is EFFIN LOUD! TOO loud for me. Granted, I have a dumped flowmaster, I can honestly say I am not happy at all with the volume.

Ugh.

 

PROBLEM SOLVED
The dealership diagnosed the issue as clogged catalytic converters. I had a local shop cut out both front and rear cats and reweld o2 bungs so I could keep the sensors. Although noise was an issue, the engine problems were solved! The noise issue was resolved with a cherry bomb glasspack followed by a Dynomax Superturbo muffler.

No codes have been thrown at all. No more lean bank, no code detecting the cats gone.

GLC nailed it!
