I've gotten through the NYS Insp., one head ache gone time to address another. My warm up idle doesn't last very long since last tune, after setting all night and early morning start up idle hit about 1500 rpm then drops to idle rpm within about 15 sec. plus or minus a few sec. I cant drive the car without it almost completely warming up. I get a get miss fires if I don't let it warm up. I'm changing plugs this afternoon. The past few morning the temperature has been in the mid 30s.
