Thanks, that is the obvious answer, right now I need to know if that is the
only problem I have. .

What I didn't have time to say earlier is that between two of the OS's
failing I did just reinstall the OEM one from last Feb. It is rather weak,
but at least it didn't ever short.

I'm kinda wondering about an electrical problem. When I start it up the volt
meter sits way to the left and then starts moving up slowly, maybe taking 12
seconds to show full charging voltage. The other day when I put in a
replacement IAC motor I did a little moving around of that two wire flat
plastic encased ground strap that bolts to the wiper motor.

When I got done I noticed that the needle moved up faster, taking only about
6 seconds to get up to voltage. But that still doesn't seem to be proper.

I guess I should take a trip to the wrecker tomorrow as see if I can figure
out how that wire should be routed and maybe get another one. I don't really
like the way that one is routed and it is touching the heater hose and a
couple of plug wires.

What bugs me is that is the only electrical problem it seems to have. When
it quits running, there is no flickering or loss of gauge function.

In a way, I am still leaning towards the cam position sensor. But when one
guy got the codes to read, that did not come up.

Thanks, Biff...

 I hope it hasn't blown out the PCM, a wrecker here quoted $275 for a used
one. Anyone have any suggestions?? Thanks, Biff
