hi to everyone,ive got an escort xr3i with a fiesta rs turbo engine fitted running on ofac management.here goes its running lumpy and misfireing on idle and kangaroos when driving up to 2000 revs,ive changed plugs and leads also co pot and idle valve and no joy,i also cut pin 2 to edis module and extended the wiring for the idle control valve,to be honest im stuck now so any help would be appreciated!!!!

 

have a look at the coil pack plug there always f*cked on the fiesta turbo for some reason, and see if the map sensor pipe is split .

 

Yeah, as above check electrical connetors for corroded pins on the MAP and EDIS. Give them a blast of WD40 while your at it.

Is this a full throttle or part throttle?

JAmes.

 

Have you got the ht leads around the right way?

 

up up as i got the problem aswell
