That's what it did on initial startup after the battery was reconnected iacv reinstalled. 4 hrs later and again this morning it wouldn't run at startup worth a damn. I just went for a 3-4 mile drive and it ran and idled okay. It was warmed up by then though. Although it's running about 200-300 lower RPM than ever before. I don't have the time today to take the iacv out. It took forever yesterday with those damn bolts and location. I would have just left the battery alone in the first place, but I hit the starter with my ratchet and scared the crap out of me when it sparked.
