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?

You can spray WD40 or something simular around the intake. If the RPM's raise, you have a leak.

WD-40 will work, but carb cleaner is better, also, check around the MAF to see if there is maybe a leak up there AFTER the MAF.

I'll give it a shot. Thanks for the advice. I'm not going to blow myself up am I?

No you wont blow your self up. I was just wondering if the IAT was unplugged while this was going on, or? I didn't understand the last part of your piece.
