NB Guys running the ms in parallel....
Do any of you get a CEL for the crank pos. sensor? I know the thing must still work if the tachometer still works but im wondering if the ecu is able to tell that its not controlling the timing anymore?

Wouldn't you check it to see if the gap is messed up?
A CEL can be caused by a single event, it doesn't mean its a constant issue, like a single misfire. How many times have you reset the code to see it come back again?
You have an issue that I don't and neither do others, so it's hard to trouble shoot a non-common issue.

FWIW, I run .020 gap on my crank position sensor. I used a caliper to measure different business cards till I found one that was .020, then stuck it between the tip on the wheel and the sensor pushed the sensor till it hit the card, tightened the bolt, removed card. Spun the motor and no interference. Then fired it up. What gap are you running?

plugs are fairly new, no more wires (thanks cops ) and im really not certain when it started...the cel was on from the start from the maf removal. Today i put in a gm map sensor to give it a fake signal and when i went to clear the codes i saw the crank sensor one in there too.

I believe Chad (cjernigan) has his in the car, plugged in, but not installed in the intake flow. As far as I knew that was just to avoid a CEL, not idle related.

Actually i've had my MAF installed in the intake path since I bought the car. I also had it plugged in to avoid CELs. I don't know how it would affect the idle.
I do know the fequency of the NB valve if you want to do some idle control, it sounds like we might need to if we want to successfully remove the MAF. I plan to leave it out with the new turbo setup so i guess i'll be using that idle mod after all
