[Shotimes] RE: swapped PCM, problem persists

[Justin Schick]

The wires were checked when I did the plugs during routine maintenance,
and checked again when I swapped the coil. But it won't hurt to look
again...

I checked the resistance on the wires between the DIS plug and the coil
pack plug, all seemed ok.

The history is that I had that little battery / tensioner incident,
then cleaned everything up and performed the aforementioned maintenance
(cleaned intake, swapped IAB, new plugs). I got a new crank sensor
yesterday and am praying it does the trick, besides the harness it's the
only ignition part I haven't replaced. My theory is if people say a
leaky waterpump can kill it, battery acid must surely be bad for it
too...

I would double check the routing of the plugs wires.

Also-Check the electrical connection at the coil pack.
Maybe try jiggling it while the car is running to see
if it dies or stops stumbling.

What was the last thing you did to the car before it
started acting like this?
