not enough info...

What all do you need to know

It starts shaking after you get to a certain speed and let off the gas a little bit to cruise, as I'd it's trying to die. Also dies while idling after startup occasionally.


did you clean the inside where the iac slides in???did you check all your vacuum hoses and spray carb cleaner around everthing?


vacuum leak lean...?

I'll check all that tommorrow while I'm changing the transmission fluid/filters ect. And let you know, thank you.

Alright, I took it back out today and cleaned where it slides in, and when I put it back in and started it, it died right away. Checked for melted/frayed wires behind the harness and it was all good. I then checked the voltage coming from the harness and it was getting the right amount.
