Ok, I went home at lunch, and replaced the coil with a brand new one.
The car started right up, ran perfect.

Used my OBD II scanner, and reset the computer, drove it around the block, and all seems to be back to normal. No new codes being thrown, I'm happy, my car'* happy, and my local Pontiac dealer can kiss my maximus gluteus.

Thanks for all the suggestions guys, I will be back with more questions I'm sure.
Like why the heck the gas hand goes all the way down then back up again.
But I'll post a new topic for that if the latest recall didn't fix it, since it was fuel related.

BTW, how much you asking for an ICM, and are they new or used?

Are you sure that he has guage sweep on his '99 SE? I know that my '97 doesn't and my gas guage started doing that before it got worse and eventually my sender failed completely.

Not trying to alarm anyone, just wanting to make sure.

Sorry...I was thinking everyone had an SSEi with the cool cluster.

Is that needle moving uphill downhill or starts and stops? Maybe a baffle is broken in the tank.

CrimsonJ, did the gas guage just start doing that?

Oh, and what exactly did they fix under recall, do you know?

That recall wouldn't have any effect on the fuel gauge.

It'* his fuel level sensor. Willing to put $100 on it. My 99 SE did the same thing. Had to replace the sending unit. I changed the pump while I was in there too.

Eventually, the guage will stop working all together.

You can see that'* where I was going with this, but didn't want to jump to conclusions.

It just does it about 3-4 times a week, and the car is driven daily about 20 miles.

It'* not uphill or downhill or anything, I've seen it do it on a level surface.
It started around November, and it hasn't gotten any worse/better.

Does this car have a float style gauge, or sensors?

I need to pick up a chilton'* or hayne'*.


We used to own a '97 SSEi. I sure am missing my supercharger.
