I recently got my car back from getting a rebuilt head put on my car...wondering if anyone knows why my RPM's now surge from like 1000rpms - 1400rpms. My boost gauge doesn't show any types of vacuum change or anything like that, and doesn't sound like i have any vacuum leaks. I also have a 2g throttle body elbow on my car think this has anything to do with it? I head it could be m throttle body just want some feedback appreciate it guys.
