This is probably what I need to do too. I know that I have a vacuum leak, well, an un-metered intake air leak, so it idles too high when warmed up, like at 1100 or so.
So, I need to find that leak.
But then today, after not driving it for a couple of weeks, it popped at idle, and popped accelerating, and popped at cruise throttle, 2-3 k rpm.
It was like the pop sometimes heard while quickly decelerating, but this was much more frequent. So, I took the car home. I have a mixture gauge already installed, but with the vacuum leak it's probably way off anyway.
Could the popping be related to air leak and mixture? Or do I have something much more serious going on that I need to check?
