we have done many engine swaps with excelent results but we have this reaccuring problem. the engine idle will fluctuate at times. we have checked the eacv, the fast idle valve, the pcv, vaccume leaks,and idle adj. does any one have a solution? thanks

 

you mean like up to about 1500 then down to 500, then up, then down? Mine does that too, only once in a great while. Kinda embarrasing at stoplights!!

 

thanks for your reply;we'll let you know how to solve that problem.
