im running around in a 1.8 zetec escort at the moment and it seems to misfire round about 4k its worse when under load ie going up a hill, been told its more than likely the tps is there anyway to check it or is it just replace and see? also do i nee to set it up or is it a one off one on affair? also when you lift off the throttle to change gears the revs hang for a few seconds could this be the same fault or would that be iscv??

Any help would be great.

 

must be some zetec boys on here that know

 

they normally suffer with flat spot or misfire at 4k, I would clean the throttle body out with carb cleaner/petrol as well as the iscv ,unlikely to be the tps or maf

 

so it is a common thing then ill go buy some carb cleaner tomorrow then

 

yes very common not unique on yours

 

cushty cheers pal
