Full size pics to show detail. The car was cleaned and waxed before the drive and after the drive, the rear was totally covered with this stuff. Does not look exactly black...more like brown shiney dust.

Car running rich or what?

 

Pollen maybe?

 

Pics are DAMN huge cannot make out what the hell it is

 

That's not some byproduct of running rich. Is your bumper black? If not, then that is something else, like pollen or something else not from the kaa.

BTW IntegraGSR23, REAL Race cars have FOUR pedals.

Only in the rear... I cleaned some of it off but it came back.

 

 

Sorry for the huge pics but it helps to make out what it is. Could the car be lean? Will probably do a spark plug change soon...

 

Take some detailed pics of the taillights since it is so hard to tell on the black paint.

 

Looks like Salt dust if you ask me. Where u from, snow any time recently?

 

No chance of snow around here.

 

My rear window Does that, Along with my Rear bumber, Tailgate, etc...

I am running a chiped ECU!

No cat!

I would not worry!

it's wax dust

yshi - who didn't know pepboys detailed cars

 

hahha

 

my car does this on the whole rear of my car, but its black spots.
i have a reprogrammed ecu, so i believe (and i hope) its because i am running rich

(i hope its not bad piston rings).

 

most hondas run rich anyways. also have you changed your plugs every 12k like you should, if not that could be the cause of your sut. bad plugs means a lot of unburnt fuel gets spit out the exhaust and back onto your car.

 

bring us a tail pipe scrape

 

look at the plugs if you want to know how the car is running.

errrrrrrrrrrrrrrrrrrrrrnt!

 

please enlighten me if that is wrong. i was under the impression that if a car was running rich, the plugs would be a dark brownish-black color and if the car was running lean, the plugs would be white. i learned this back in go-karts so it might not carry over...

Uhm, doesnt this happen to all cars. I think its simply dust that collects on the entire surface of the bumper and rear hatch due to static.

 

my car doens't do that and i know for a fact my car is running rich. (mugen chip)

 

actually, its hard to tell its running rich or lean just by pulling the plug out and see. since all the shitty gas and u are running lean at idle. the only way to tell is to use pro A/F meter.

 

errrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrnt again. anyone want to try one more time?

 

Can't be that since it is black when I wipe it off. Why does it look white!?
