Here goes,
sorry for the essay
ive got a 1998 escort gti it wasnt idling properly when first started it was hunting then when I was stopping a traffic lights the revs were dropping to arround 500 rpm it was drinking like anything doing about 18 mpg,
so I did a bit of research and thought id clean out the idle controll valve so I did that today and while I was doing that cleaned the throttle body as it had all black build up in it and was a bit corroded, oh also the inlet manifolf had a big puddle of petrol in it.

so I got it all back together and now the car starts up at about 2000 rpm on all four then the revs drop to nearly dying point then chugs on two cylinders and but if I put the revs up myself it goes up fine but then gradualy goes down and misfires like anything.

all hoses pipes and wires are all on properly aswell,
please help me sombody,thanks in advance neil.
