Zetec turbo on megasquirt, car starts fine but idles high and hunts and if u rev it it doesn't want to come down... Wen u drive it because the idle is up n down wen u pull off it jumps about and drives rough, wen u put ur foot down more tho it seems to clear n comes on boost ok.

Thinkin air leak bit can find an obvious leak????

Any help for trouble shooting muchly grateful 👍

There is a setting in tuner studio that can make it idle really badly like your describing, I will load mine up now and see if I can see which one it is.

Edit to add I aint got a clue what setting it was after having a look.
