I'm new to the logging and scanning. I had my PCM program by Bryan, and haven't changed anything. I was getting a rough idle, other than that, the car seems to run perfect. I noticed my IAC counts are in the low teens. When I switch AC on it goes up 10 counts and actually idles better. How do I fix this. I also noticed my knock count stays at 2144 the whole time, what's this mean. I do have a desensitize knock sensor by 50% and a LT4 KM. My right and left BLM's look to be slightly different at times also. Anybody want to take a look and offer advice? Thanks.
