Camaro Eforce Cammed Idle problem when Neutral gear
Just bought a Camaro with Eforce supercharger and a custom cam.
Car runs fine but when putting car in neutral, the rpm goes up to 1900rpm for 6-7seconds, then drop down at 600-700. It also goes down to 600 as soon as i hit the clutch pedal. Would like to know what can cause this and where to look. I'll put off TB tonight to clean it up and brake Booster Vaccum hose seems to be in good shape. Thanks, Kevin |

Either you have a vacuum leak, or your vehicle is not properly calibrated.

Agree. Likely a tuning issue.

are you setting still or coasting down the road when you put it in neutral and it idle's up ? if your are coasting in neutral and come to a complete stop(speedo at 0)does the idle return to normal?

Drove the car yesterday, no engine light and no idle problem. I think i had some humidity froze in a sensor... coming from Florida to Montreal at -25C. I think it was the problem since its allright now.
