Exhaust leaks back there won't do it.

You only half-tested your coils. Please follow the Techinfo procedure.

You know what. May its my foot. When I start acceleration my rpm'* are almost 3000. And I'm guessing the lack of power is from my CAI. I have heating duct but didn't make a box out of lexan. I'm going to add a hose thing to supply my CAI area with cool air. I didn't do any rough acceleration today and I'm getting fair mileage, but I'll see. And the primaries tested between 5.3 - 5.8. Now I'm finna go stunt and pimp a couple hoes .

You mean your SECONDARIES measured that.

That would be foolish, considering it could be any one of 100 things, and we've really never even seen a faulty knock sensor on this entire Forum in 5 years. Let'* not toss 'might be'*' out there at this point. That can get costly.

Ummm let me go check the coils right now. Also, I ran the scantool and my KR was zero and no codes. Unless my knock sensor is just broke. I'll be back

Didn't find anything unusual except a spider that was living under my coil pack. I had to kick his *** out even though he was dead, but rent aint free. The primairie readings with my meter set at 20K was .02 for all three

You set your meter on the 20k scale? For less than 1-ohm readings?

Ok, rule out the coils.

Now wait for dark, get some water in a windex sprayer (well water is preferred over city water), and spray down the plug wires while it idles in the dark. Look for arcs. Let us know if you find any.

Nope I didn't see any arc'*. If it helps, to add to my symptoms, sometimes when I start my car up It doesn't start smooth. its acts like it pushes out a lot of air out the exhaust. But I dont see any smoke.

EDIT: One of my lifters is ticking also, I dont know how this contributes to my lack of get up and mpg though.
