It never does this till it warms up. And sometimes it stops for awhile once its been driven some.
Here's what its doing. At idle in park or in gear, it will drop from 700 rpm down to 500 rpm to the point of almost stalling, dash lights/headlights dim the whole 9 yards.
I thought it was a vacuum leak, but darned if I can find it.
It doesn't run particularly rough when being driven. Slight lack of power maybe??
Its my wife's car so I don't drive it often enough to know for sure.
Any idea's on what could be causing this??

Thanks
Jamie.

 

It might be the ETM. Has it been replaced with a new one under warranty?

 

I'm really not sure. We bought it used. I don't think we've replaced it though.

 

a buck says it's your ETM. perhaps it's defective or just dirty

here's a vid on how to clean it

Great video! Thanks. That's exactly how here car is running. I'm going to try and clean it and see what happens. Hopefully that'll. Do it though.

Thanks again.

could also be an o2 sensor.... its worth a check

 

Man, I hope not she had 4 of those replaced last year.

 

Yep, the ETM was really dirty. Cleaned it up, and she's running like a new car!!
Thanks again for the video link.
