Someone i know has an escos and its running a bit badly at mo,wen it gets to running temp it starts reving up n down by itself,and wen he accelerates its goes alright till you back off then accelerate again and it has a flat spot on acceleration so far he has changed throttle postion switch,dizzy cap,rotor arm,coil,ignition amp,plugs,and has disconnected the amal valve and fitted ableed valve and its still doing it,anyone have any ideas??

Cheers

 

my 4x4 saffs doing exactly the same, but running really rich as well, i was thinking may be the diaphram in the fuel pressure regulator split, or temp sensor for the ecu but not had time to check it yet
