[QUOTE="03' White Snake, post: 16062961, member: 51916"] Just an FYI, my car starts and idles very rough on cold days on E85. It pops and backfires in the exhaust. Can barely back it out of the garage to let it warm up before driving it. After it warms up it is fine. What gap are you running? How much Boost? Check your boost bypass is actually working, mine idles like crap if this is not working. Should be open during idle and close under light throttle. Possible vacuum leak? How much vacuum you pulling at idle? You want the largest gap possible without spark blow out. I'm running 22 psi and my plugs are gapped at 0.028". I've heard people running down to 0.022" with high boost. [/QUOTE]
