In that case, I just need to "rent" an AFC. I asked the guys over at IACGP if anyone has an AFC I could use for a day

Yeah you could but still, you don't want to be running around with KR.

Tonight I was cruising around town running errands when the CEL turned on. The code is a P0300 Random/Multiple Misfire Detected. I assume it'* just the cam, as it happened while I was sitting at a stop light, but for some reason I just started getting nervous about this thing. I don't want to break any hard parts or burn up the motor, and this extreme lean condition can't be good. I hope I'm not doing damage already. The car started running about 10 degrees hotter by the time I parked it, and I may be crazy but I think there'* a tiny bit of a burning smell. I'm not completely sure that I should even run the motor anymore without an altered PCM or AFC. Here'* hoping there'* nothing being ruined already .

And for my third post in a row.....


I've decided that the car will not be run again until I get a Mini AFC hooked up. I'm already scared that I've done damage to the engine, so there'* no way I'm going to run it until I can adjust the fueling curve.

Thanks Mike..... I had actually looked at two of those threads already, and sent a PM to one of them . I appreciate it!

In reference to my other worries.... do you think it'* possible I've already damaged some internals?

EDIT: I just checked IACGP, and this guy'* statement makes me sick

Your lean condition at low load conditions would increase the operating temperatures drastically. There'* a high possibility of damage. However, I like to be optimistic and will say the lean condition fried your spark plugs, so that'* why you are getting a miss.

Gauging from my personal experience, I doubt it. I was running with a max of 9* of KR (from buring oil) for a while actually. I wouldn't get it unless I really got on it so for the most part I was nice to my engine. If you don't beat on it, run 91+ octane, watch your engine temp, and just pay close attention I *think* you'll be fine. That'* my opinion. But know that the safest thing you can do is park it untill you can get that fueling corrected.
You should pull your plugs to see whats goin on too.

I'd like to hope that everything is still alright. I've got Autolite 104s in right now with 93 octane and three cans of octane boost... I wanted to make sure I was killing all the KR I could.

But I'll just drop it for now, because there'* no use speculating. If something turns out to be damaged, I'll deal with it when the time comes. Otherwise I'll just run around in circles worrying about whether it'* damaged or not. So I'll just cross that bridge when I get there.

Haven't heard any responses on CGP yet...

I'm doubting the validity of your scan data. Can you get an Autotap on there?
