Hi Huys got a question about my car I just purchased when you start the cart and run it for a while the idle won't go below 1500 RPM'S what should I look at first. also it does have a Paxton Novi 2000 supercharger on it
Thanks Bryan

check for vacume leaks at your IAC valve hose that comes off the intake.
Also check your PCV valve hose at both ends.
