Help Please!
Today when I started my car the RPMs went up like I hadmy foot stomped on the gas. I killed it checked the pedal and TB. Started it again 3 times same thing. Can yall help me?
If your throttle blades are closed all the way, it sounds like you have a large vacuum leak somewhere. Check the PCV valve hose and the brake booster hose for leaks first, then check around the plenum and runners. Ether or propane work wonders for locating leaks.
