yup...rich. Those are exactly how my plugs looked when I took them out...maybe even more black. That's why I have to get this f*cker retuned before expo!

Hrmmm...

Something happened to the car while I was driving last night and now it feels like complete ass.

Here is how it happened.
End of fourth gear 100% throttle and the motor just went silent!
comes back after I let go of the gas and now is struggling to make power.
On the streets toward my house it has a hard time reaching 3000rpm then kinda clears up and revs a bit easier, but still with some hesitation.
The car will idle fine, no misses or anything.

Later today I'm going to check all the wire connections under the hood, then TAKE OUT the VAFC and see what happens.
Any other thoughts?
PLease toss them in

Limp mode? That's my only guess. Seems to me like I had a similar problem with a car once, but I have forgotton how I fixed it.

I would take a close look at the VAFC wiring and calibration, mine liked to reset itself once in a while for no reason

No limp mode... After I can get it above 3k rpm it will go.... So i highly doubt it's limp mode.

As for the wiring for the VAFC, I strongly suspect that is the problem. I'll be checking it and then taking out the damm thing. Unless it's a single wire that caused the problem.

Is there any plugs under the hood that could have worked themself loose and caused this? Like say a injector plug?

I think an injector plug missing would be more noticable... this definitely is something altering the fuel map. Those plugs seem very dark, but it could be the flash.

if the headlight fluid is topped off, then KISS and unhook the vafc..

Does it seem to be throttle position related? I've had problems where the car pulls nice and strong at partial throttle but wot falls on its face.

Funny you say that, two of my injector plugs popped out like 2 weeks ago, and I was runing on two cylinders. Had all the same symptoms just like you described. Did you check if all 4 of the plugs are getting spark?

So I spent some time out in the cold and changed the fuel filter and removed the VAFC and the car is back to normal. When I took off the VAFC all the connections were solid, nothing loose at all... I guess unit failed

Well thanks for the help guys.
