Idling Problem (Clutch?) - Longish read sorry.

[Michael172]

Hi guys, having some problem with the Dynarat. So my initial guess was that the clutch is on its way out.

Basically, usually itll idle at ~800rpm, so whether im coming to a junction and i have the clutch engaged or its sitting there, itll idle at that same old speed.

Recently however, ive been finding that when i engage the clutch and im still moving (And for about 8 seconds after i stop and become stationary) it will idle at about 1500rpm, and then eventually go down again to its normal idle. The Clutch feels fine, although ive always thought its been made from pastry and chaning from 1st up into second can make the car judder a bit (Doesnt happen usually only on rare occasions).

But then i came across something else today, and im not sure if its related or not. I got home and parked up, so as usual it sits there idling at 1500rpm and eventually dies down to the norm. I switch off, and out of curiosity switch it back on again. It starts idling at 1500rpm ffs, when the engine is cold it idles at this speed for a bit, but ive just done a 20 minute journey so the engine was very warm, look at the temp guage, and its stone cold , about 20 seconds later it realises that actually its fully warm and starts to idle as normal.


So any ideas? Is my clutch dying or is there something else you think could be the matter with it ? Hopefully gunna get My friend over to look at it (Mechanic) but id like your opinion. Thanks for the help, if i get any.

NB:

I have the later 1.2 16v MK2 PH2 Engine found in the MK3, so electronic throttle.

Sure I have read something on here to do with either the idle control valve or the throttle body (your type) being the cause of this problem.....hopefully some one with a better memory will help you out....

Mine is similar but my revs drop down to a stall sometimes then it dies

 

[Michael172]

Well im putting down to the clutch or the temp sensor. Told my friend about it and he thinks itll be the sensor so im hoping it wont cost me too much.

 

[Michael172]

Defo the temp sensor, could someone tell me where its located on the new D type engines please ?

Am i looking at an expensive job ??

I know it's a different car but my old Escort use to do something similar, I knew it was clutch related because it use to slip, eventually when I took it in to be looked at I was told it was the thrust bearing.

I know it's a different car but my old Escort use to do something similar, mine use to rev up to 2k revs though. I knew it was clutch related because it use to slip, eventually when I took it in to be looked at I was told it was the thrust bearing.

 

[Michael172]

Well, considering that each time it does it, the temp guage on the dash goes down to cold, that kinda gives it away tbh.

yea temp sensor is on the thermostat houseing or on the gearbox end or the head.

My 182 did the same sort of thing, temp would drop down and the car would go back to fast idle! If i rev'ed it hard the car would run fine for about 500 miles or so, however since i had it re-mapped it hasn't done it again!
