Thanks Ed but I don't have a scope. And by the time I load up the car and take it to someone that does and knows how to use it. It would be much cheaper to just throw the parts at it.

He could try making the gap slightly less or more and see if it effects the running. Most VR sensors run best @ .050 gap, check the resistance of the sensor, you can also hook up a DVOM set to AC volts with sensor unhooked crank engine sensor should produce about 1 volt AC while cranking.

I'll check the air gap on the crank sensor and try to check the sensor. Can I just hook up the wires to my volt meter (AC mode). And then crank the motor over with the starter?
I did move some wires around when I changed intakes and converters, I'll take a look to make sure nothing is running close and parallel.
