[Shotimes] Getting Very Frustrated - Random Stalling

[Ian Fisher]

The intermittent stalling on my previous SHO (94 atx)
was caused by a loose wire inside of the coil pack
connector. This was one of those "once in a blue moon
things" that we figured out after tearing the entire
front of the motor apart to replace the CPS (replaced
the water pump and timing belt while we were in there
anyway). I started the car back up and it stalled
again. We started shaking parts of the wiring harness
as the car was running and that's how we found the
problem. Just an FYI-it probably isn't your problem
but it doesn't hurt to try this. I would focus on the
DIS area and the coil pack.

You didn't recently have the intake off or
painted/powdercoated, did you? The DIS relies on the
intake being torqued completely and unpainted behind
the DIS and the ground bolts for it to work properly.

good luck
Ian
