Heavy Soot Accumulation

Although I've ditched the CAI reverted to stock and reset the computer one week (~900 miles) ago, I'm still getting a lot of heavy soot accumulating on the bumper and rear surfaces of my car...inside the exhaust pipes is caked with the crap.

This thing is either still running very rich, or it is somehow not burning all the fuel thrown at it (which is another way of saying it's running rich).

I called the dealer, who of course said off the bat that "If it were running rich, you'd have a check engine light."

"Trust me. It's burning fuel in the pipes. Why it hasn't thrown a code, I dunno."

So, I've an appointment on Tuesday so that they can throw the thing up on the racks to determine WTF.

This car is really beginning to frustrate the crap outta me.

It's pissing me off, be sure.

I'm just voicing frustration here. Yes, I push my equipment hard but, damnit, I take good care of it as well.

...And God help the service guy who tells me this expelling of particulates is "normal." If he does, I'll tell him, "Fine. Smog the car. Now."

Hey Grouchy,

My new 05 really cakes up the chrome tips. Every time I wash the car I take my wheel brush and wheel cleaner to the tips and scrub like heck to get it off them, but I have never seen any of it on the body. If its heavy enough to get on your bumper cant you see it smoking black? Its really gotta be comin outta there like crazy.

Yeah right. Like someone is going to be able to keep up with you, let alone look for smoke. Maybe it's something YOU'RE smoking. LOL

The black inside the tail pipes is a common occurence with unleaded fuel. To cover the rear fascia isn't.
