Here are a list of my current symptoms:
(They only present about 30-40% of the time that I am driving)

1. Occasional stalls during slow sharp turns or reverse
2. Rough ride, with RPMs jumping all over the place
3. Codes for cylindar misfires
4. When I hit 70 mph exactly, car goes in to freewheel until it gets
below around 67 mph


This has been going on since Thanksgiving. I have had the following
work done so far:
1. New crankshaft sensor
2. Throttle body clean
3. New spark plugs/coils
4. Engine reflash

The ECM I got was only $100 bucks, so I figured I'd give it a try.
The techs at all the places I have been to say that it isn't the
ignition switch, but I will ask again when I go in tomorrow to get my
ECM reprogrammed.
