Idle problem, Smell problem
First problem I am having is fluctuating idle. My idle has always been fairly low, but recently it seems different every time I turn on the car. Sometimes when I turn it on, I will be idling from 1500-1600 rpm's or more, and sometimes it won't even be 1000 rpms and sit around 900 or less. When it is sitting over 1500, I will rev from park just a little bit and then it will fall to smaller idle. After driving/while in traffic, my idle will be closer to 500 rpms. So as you see, there is no constant and it has been worrying me. My car has also just "felt" like it hasn't been running great lately and so I was wondering what could be causing this day-to-day fluctuation?
Second, the last few days upon turning on my A/C I am getting a somewhat rotten smell, anyone know what that may be coming from?
Ps- My only mods are a catback and AP stage 1.
Sorry for the long story folks, but I appreciate the help
