so after my tune in December on my lq4 z28 i experienced some cold start problems. those were taken care of by adjusting the A/F. now that its hotter weather my car starts up strong to about 2500rpm and just hangs there at a high rev for a moment before dropping completely down and turning off. sometimes this will happen up to four times before it will catch idle by itself. does the A/F need to be adjusted for the new temp of summer? thx guys this is my first tune!
