What's up guys! I have a question. So recently I've been noticing my AFR is constantly fluctuating at idle, usually on cold start up it's in the 15 range and once I start driving I have to pursuadd it a bit then it goes to optimal range. but during driving it stays in the 14.7 to 14.5 range. I've checked all the usual spots for boost/ vacuum leaks and can't seem to find anything out of the ordinary. Are there any weak points for leaks to happen? I have a 16 full bolt ons.
