1998 Escort 1.8 Si -> Sticking Revs

All,

I have been reading lots of posts about my car, and i wish to have a few people confirm my thoughts....

1 ) my 1.8 si Escort is great, except that recently the revs have started to get stuck at anywhere between 2000 and 3000 rpm. My journey on the motor way involves mostly at 3000rpm, and when slowing down, the revs drop with the slowing of the car ( leave it in 5th and slow the engine down ) but as soon as the clutch is released ( pressed to the floor ) the revs sometimes rise to 2000 rpm... sometimes it drops straight away, other times can take 30secs or more.

when driving normally, if the car is moving and I dip the clutch at

3000 rpm, the revs fall to 2000, then they sometimes stay there for a few seconds and continue dropping....

Is this a faulty Throttle position Sensor? I have taken the throttle body off, cleaned it out with car cleaner. I took the TPS off, but its a sealed unit so i could not clean it.

I want to take the ISCV off and clean that too, but it looks such a b*gger to get to, and one bolt seems to be obstructed by te starter main feed.

I spoke to Fords parts who said its £56.93 + vat for the small piece of plastic.

Can i have as many peoples thoughts on this as possible please.

Also,

2) the car heats up normally, but once warm, the temp gauge sits in the middle of the "cool square", and sometimes off the bottom of the gauge. This mainly happens while moving, and when stationary, it rises again back to the N of Normal.

Is this a lazy / stuck thermostat? my house mates car is also an escort Zetec and his does exactly the same???

If it is a faultly thermostat, could it effect my mpg?

thanks for your help in advance,

Ian.

Certainly sounds like it. 'er indoors has a 1.6 and that definately crawls out of the blue square and stays out.

Ho yus!

Regarding the temp gauge it will probably be temp sender which is located in the head,mine did this on my mondeo zetec,just have to be carefull to replace it with the correct colour coded plastic top,it will have a single push on connector about 10mm i think, Regarding the revs it's most likely the 'iscv' again common fault but a pig to get too.

Almost certainly, and definitely. I would replace this before tackling the other problem because never warming up can make an engine act funny.
