ive got a ford escort 1998 S Reg 1.6 Ghia
car drives fine very smooth etc..
but when i start the car up it rev's it self up to 3000 revs and the back down to 1000 and it looks like its about to cut out but it doesnt cut out
when i drive the car its fine doesnt rev it self
but when i change gears you get the feeling the engine is rev'ing it self..
also there is a rattle from under the engine ive not been able to look to see what is rattling but could this be a link to the engine rev'ing it self??
when i rev the car in park the engine is fine and there is no rattle
can someone please advice me on how to repair the rev'ing problem??
