ok guys i need some help......ive built quite a few honda motors in my day, but i have never had this happen and its really starting to piss me off. i recently bought a del sol s (s stands for slllllooooow) and im in the process of building a d16z6 for boost to swap in. but the sol is my daily driver and the 4 horsepower it had at the wheels just wasnt cutting it, so while im building my turbo d i decided to slap on a spare z6 head i had and make a mini me. the car starts fine and drives fine, but idling is a whole different story. it surges, it cant decide whether it wants to idle high or low, sometimes its chillin at like 1500 and sometimes its bouncing back and forth from 500 to 700.....and other times it just sits around 1000. here are the things i have tried: new intake filter, new plugs, new plug wires, new pcv valve, new dizzy cap and rotor, cleaned fitv. there dont seem to be any vacuum leaks anywhere either ive been over and over the whole vacuum system.....i just cant seem to figure out how to get this bad boy to sit at 650 like it should. any ideas? i am leaving for savannah tomorrow and the car is ok to drive but this shit is getting annoying.
