S3C Cutting out and hesitation when cold (+ Hoop bolts)

[LawrieS]

Experiencing a minor problem with my S3C, i've noticed it before but it's definitely getting worse.

Only apparent when cold but approaching junctions, clutch in and it will cut out, or almost cut out, enough to relight the charging lamp.

Also notable hesitation, seems to be worse the more throttle is applied, almost to the point of 'kangarooing', though obviously tend not to floor it when cold.

All appears fine once warmed up (which does take a while, suspect thermostat stuck open).

Any idea's? I do have a new ICV to fit but not tried yet (though it has been on and off a particular car a few times in a wet Luxembourg lay by )

Possible suspect TPS? I've been meaning to add one of these to my spares collection for a while but never find a sensibly priced one, could anyone recommend a source?

Any other things to check?

Whilst I'm at it, noticed when putting the roof back on tonight that the (pivot) bolt on the passenger side of the roof hoop is a bit loose, tried turning by hand but it never tightened up, how does it fix? Captive nut? Or is more revealed when delving further behind the hood material?

Had the indicators fail but that's now sorted, hazard switch on and off now all back to normal

Shouldn't have been praising how well it's been running at the weekend

Thanks in advance.

It is just a nut, which may well have rusted and seized. You need to get your hand in behind the carpet and into the void between the outer skin and the inner skin which the pivot bolt goes through. Stock up with PlusGas and Elastoplasts. Good luck

PS - there is an 'S' rad for sale on Facebook if you're interested.

Hi Lawrie,
First make sure your AFM vanes are nice & clean. Use carb & choke cleaner and a soft brush or cotton buds. Careful as they are quite delicate.

Barry had the same probs, it cured them on his S2.

No AFM's, as per Percy

Oh yeah! I guess the clue was in the 'S3C' in your opening post Lawrie.
( I had just got back from thirstday club though )
