Since I've fixed my major problem... moving on...

[sirius_GTO]

Since I've fixed my major shimmy problem, I'm moving on to the next.

I'm in Iowa, so it gets decently cold here. SOME TIMES in the morning, my car stutters when I'm at a stop light at idle. I notice that if I turn the heat or AC on full blast, the car's rpm will decrease until it dies.

It doesn't affect driving because it still drives beautiful.

But the check engine light IS on. I'm thinking that it's a fuel pump issue. Anyone else?

Also, my heat doesn't blow out hot air when I'm at idle. Only when I'm driving will it. Any ideas? Thanks guys!

could be the temp sensor for the DME
