Hey Blazer Gurus,
Need some help locating/adjusting/testing the 'air idle control motor' thingie....The engine runs fine, but after warmed up, it develops a
weird miss at idle...my son thinks it's the AICM.....but I don't have a clue where it is, or if it's 'adjustable' or one of those nice 'R&R' electronic gadgets....Can someone toss me a line here? I you hold the idle up a bit, there is no more 'miss'...perhaps set too low??
Thanks,
GT
