Hello Ford fans,

I have recently purchased a '99 Mk 1 Focus 1.8 Zetec. For some reason the engine revs continue to go up when I take my foot off the accelerator to change gear, this is even worse when the engine is cold. Should it do this?! I have adapted my driving by taking my foot off the accelerator, pausing a couple of seconds and then changing gear. Otherwise if runs well (touch wood!!). I was hoping it was just a sticking accelerator cable but I suspect it's more to do with the engine management. When I am stationary the revs initially stay quite high (not crazy high - like 2000) then drop down to a good tickover. It was recently given a "health check" by Ford when they replaced cambelt and they didn't mention it (but then nor did I!).

Sorry if this is a stupid question! Any advice would be gratefully received :-)

Many thanks. Chris

Get the throttle position sensor and idle control values checked out.
I used to get that on my Mk1 and it was the icv.

Ok, thanks. According to the manual I have removal is tricky and according to eBay new ones are around the £50 mark, is this the sort of thing that can be bought second hand? Any cheaper sources out there...?

Cheers.

To be honest I'd edge towards new parts for that.

it may be worth going to ford if you want to saue money and have it checked as said you have the icv an throttle sensor it can also be a leaky vacume hose stuck pcv valve or a coked up and sticking butterfly valve you could buy 3 of these parts and find the fix or have it diagnosed and buy 1part i wouldnt buy 2nd hand parts how do you know they work
