Ever since i have had a new engine fitted in my ph1 172...
 
When i release the throttle the revs stick at 2krpm sometimes higher... then when i tap the throttle from the underneath the revs go back to normal..
 
This only seems to happen after running the car for over 20 minutes and my car sounds like a tank when i pull up at the traffic lights... ahh
 
help guys?
