172 Mk1 idle problem

[mr bognor]

Not to sure what this is . Im running the old mans car / my old one till get something soon and the idle is realy rough and not smoth if that makes sence some times sounds like its going to die but never does and drives spot on just this idle that does not sound right ??? The car has been run on 95 ron for the last couple of weeks and just had a new coil pack and lambda sensor. Does the lambda sensor need a few miles to work right ???

Any help would be great

Hmmm, do you mean it struggles to idle mate, as if its going to stall or does it rev itself?

Not realy it idles ok and does not hunt or anything and does not ever die just every now and then it sounds like it is going to die and then is ok ??? but just realy lumpy on tick over

Just been out in it again and thinking is it just a rough idle . Car runs spot on nice power no flat spots good mpg ??? Is this just how they are on idle . It idles rough cold, warm does not matter .

Look at this thread:

Specifically Adam172's bit about the ICV changing, I'd try this as its a cheap fix and your issue sounds to have the correct symptoms.

And this post (towards the end) to see some pics of what he had to change
