Do I have a vacuum leak? My idle has been acting a little funny. It tends to go up about 100-150rpms as the engine becomes warm. Additionally, when I'm in 4th and I hit the throttle hard, it sounds like I'm getting some pinging. And lastly, when the car is warm and I shut down the engine and then restart it, my idle will sometimes rythmicly surge by about 50 rpms. It used to do it up to almost a hundred rpms, but it has stopped reving as much and the frequency of occurances has gone down. My mods are: lid, bauer tb, and a cutout. This happens whether or not the cutout is capped. I have Atap on it's way to help me diagnose the issue, but I'm kinda impatient 
. I had recently resent my PCM to clear a code (forgot to hook up IAT sensor). Would this account for the behavior?
