fried rings would cause blue smoke not black, black smoke is over fueling like you put it overall rich

coolant... typically, blown headgasket... that or it's an Uber-Kool smoke screen! :love:
thats what i figured,but i changed my knock sensor and the fuel presure regulator and still black smoke and 100 dollars comming out the muffler.I give up,not.626na;1106063 said:
the timing is fine, thoe my first injector black washer looks to be chiped but don't see or smell any strong gas sent.CRE;1106652 said:
You sure the timing is mechanically correct too? What the timing light says isn't all there is to it... just in case you don't already know that.
Hear any hissing from it? A crack large enough to pass air in the injector washer can allow a lot of unaccounted for air into the cylinder... not really a good thing. That won't make you run rich... lean on one cylinder if anything.
And you still haven't answered the question as to whether or not there are any diagnostic codes stored.

i have one code for the engine that is 31 i believe dealing with the m.a.f sensor.CRE;1106729 said:
Uh.... hello?
You've got a diagnostic error code stored for the VAF and you're thinking your rings are making you run rich? Sorry, but, do you know what an air flow meter does.
EDIT: Testing procedures are here:

BTW, the acronym MAF is most commonly associated with Hot Wire type air flow meters... Don't find these in any model of MKIII. The MA70 (MKIII with a 7M type engine) uses either a VAF (Vane Air Flow, 7M-GE) or a KVAF (Karman Vortex Air Flowm, 7M-GTE), when referred to generically AFM (air flow meter) is the preferred acronym. You'll get a lot of argument asking for a MAF for a 7M in a parts store.

Thanks for the supra 101 lesson.:icon_redf and knowing is half the battle,l.o.l.after i forgot to plug in my afm i turned the engine on and the fan severed the wires and i had to rewire them and covered them with electrical tape temporarily. before this misshap it was'nt running rich.I think the fan might of made a short in the harnes.what do you think?CRE;1106986 said:Uh.... hello?

No problem, and it sounds like you know where to look for the source of the trouble.
I updated my post a little too, in case you didn't see. If you want to know more about how the systems vary check this out:
