I just got a '95 civic with a gsr swap & I am having trouble with a high idle. (2000-2500rpm) I have done all the obvious stuff, idle screw all the way in, no apparent vacume leaks, check thermastat on the iacv, check that the plastic ring is screwed all the way in on the iacv. Also, if it matters the car has a msd distibutor & coil. Any one got any suggestions? I am new to Hondas having just come over from the world of big carbd V8s.
