hi all i have a ford escort gti 1.8 zetec it has 75k and im getting problems.
-first of all its blue smoking when i push it up to about 6k rpm but it doesnt do it below this rpm, could it be rings? thought rings smoked all the time?
-sometimes souinds like its running on 3 cylinders? coil pack? i put new plugs and leads in it last night and it did it again today!
-hesitates when cold.

i have only had the car 2 weeks and im a bit annoyed as i want to go out and have fun rather than worry about it blowing up!!
if anyone can help i would appreciate it alot! or even anyone who could supply me with a new engine would be great! thanks
