black sh*t on rear bumper?

yellowstang98 · February 15th, 2009, 08:57 PM

why would there be a build up of black "sh*t" on my rear bumper? It is right where my exhaust pipes are, and I understand that is obviously from the exhaust, but what exactly? Its like I'm running a diesel! Thanks

Have you been getting butt fucked by your car's exhaust tips? That would explain shit on the bumper.

backed into a defecating cow?

Is there anyone over the age of 13 out there that would like to respond? I don't mind the jokes but you could at least provide some insight along with your humor...

Sorry man but I don't have a clue otherwise I would have said something.

That's the only thing I can think of, but that doesn't help him a whole lot. Have you thrown any codes or done any new mods to your car recently.

post a pic if you can please.

Breakout · February 16th, 2009, 09:48 AM

when was the last time you did a tune up? Might not be burning all the fuel...those are the only 2 things i can think of at the moment.

Would definitely help.

I mean, you did say black shit....so it sounds like you already discovered what it is!

yellowstang98 · February 16th, 2009, 03:07 PM

I was thinking Im runnin rich too. I've been having some issues with my idle so I was going to replace my plugs and wires and clean my TB and plenum. I really noticed after I got the prochamber and flowmasters installed. I didn't think Id need a custom tune tho with mods I have but maybe I do. Thanks for the help. Ill post a picture later tonight too. Thanks again!

Mach Boy · February 16th, 2009, 05:32 PM

You probably will need a tune. I only had a RAI and exhaust and I was running lean.

mustanginky · February 16th, 2009, 05:49 PM

yup unless you have cats on that prochamber you need a tune. it messes up the 02 readings. You'll have to get a tune, it's most likely just rich as hell. have a friend watch you stomp on it and see if she blows black smoke.

yellowstang98 · February 16th, 2009, 06:10 PM

No cats with the prochamber. guess that's the reason then. looks like im going to have to put out the 500 it costs to get a damn tune! that sucks! think if I get a diablosport tuner I could adjust it myself? would def be cheaper!

Mach Boy · February 16th, 2009, 06:36 PM

Yeah unless you screw up the tune then it could be a lot more expensive. I'd say spend the extra green and get it done right.

blakehunter316 · February 18th, 2009, 09:56 PM

spend the extra cash. Not much more plus its a hell of a better tune prolly dyno alittle higher numbers with a custom tune too.

~C~ · February 19th, 2009, 08:25 AM

All you need to buy is the tuner. You havent changed much so you can pick up an xcal or a diablo and turn the o2 sensors off. Should run fine. However, a custom tune and dyno would yield some more power, but in an effort to save the greenback, that is all you really need to do.

And i just wanted to add that post number 4 was pure
