My 87 NA has been sitting for about a year and i started it today and the idile will be fine then drop to whare it sounds like its going to die then climb up agine. It sounds like its about to die then someone hits the gas to stop from doing so. I think it might be the O2 sensore but im not sure What do you guys think?
Thanx

Wow sorry im realy tired and out of it and spelled Idle wrong.

 

I think that if it sat for a year, you probably have bad gas in the tank..

 

No i thought of that too. I drained all the gas went and bought 5 gallons and filled it up with clean stuff.
