Default Revving!!

Hi I have a 143 vvc engine and on idle its 1500rpm. And when driving the revs seem to creep upto 3k on there own. Also after acceleration and slowing down the car holds revs at 3k and you have to blip the throttle to get it to drop. But only drops down to 1500. Over fuelling really bad as can smell it in the car. I run a cone filter directly from the throttle body. I've changed the stepper motor twice for new parts as I thought first was faulty. I dont have an obd port.
Any ideas???? As its annoying and embarrassing at times.

Ben

Sounds like temp sensor if it smells like it is over fuelling, before buying parts though Iíd check for any air leaks, I doubt a compression check is necessary.

I assume the idle adjustment screw makes no difference to getting it to idle to less than 1500?

Do you have a plastic throttle body on it?
Theyíre prone to sticking, if thatís the case then the best thing you can do is upgrade to the alloy type and then you may aswell stock a 52mm one on

Are you sure the throttle cable has no tight curves in it so the cable returned home every time you take your foot off the gas?

Idle at just under 1k is about right. It's just keeping it steady...

Have changed the cable today just to rule it out but it's still revving up. Not all the time now tho. But 3 out of 5. Just seems weird how its bang on 3k wen it revs up on it's own never above or below but bang on 3k. Have checked vacuum hoses and all appear to be in good condition

If you leave the air filter off does it still do it, the sticking plastic TB sometimes isnít solved by just cleaning it, air filters that are clamped on can distort it and prevent it from closing.
With the air filter off it may still do it, try pressing on the butterfly inside the TB to gently force it closed, if it is sticking then that should hopefully prove it is the issue, do yourself a favour and bolt on a 52mm TB.
