hey, i've been noticing all this black crap coming out of my exhuast and getting all over my **** in my garage. i believe its unburnt fuel caused by a faulty/gummed up o2 sensor... anyone have any knowledge?

 

Kinda looks like oil spots.

nah,my old turbo integra did the same thing turns out i was runnin real rich

 

Did it just start?

 

that happened to me... you my friend are running really rich... im assuming you are running a chipped ECU?

 

Does your back bumper look like mine?



This is after rinsing it off...

 

i do have a chipped ecu, but i just got the chip and this has been happening for some time now. i have a del sol so my bumper is angled differently and that black **** cant make its way up that way, but i do have black marks above my exhaust.

im almost 100% i have a shitty o2, but i was just seein everyone's 2c

 

i would try and get your chip retuned...

 

Could it be a faulty plug, wire, or dizzy cap that isn't working fully and letting unburned fuel through, are you backfiring?

backfiring a little, the guy is sending me a new chip today, the cap/rotor/wires are pretty old im actually trying to save up to buy a new o2 since ive never changed it and its all black. im backfiring a little but its not that bad. i think i might have a bad coil but i dont think thats related...
