my stutter, well my cars anyway ???

[vinnie m]

do any of you guys know what is causing this?

done about 2000 miles since supersport-R converstion and on 4 different occasions now I have had a bad stutter from the car, Feels like fuel stavation.

Anyway each time this has happened it is after a long run then a short break (anything from 2 mins to 20 mins) then fire her up, pull away and a kangeroo up the road.

seems to clear after about quater of a mile but is a bit worrying

any ideas PLEASE!!!

This would most likely be heat soak, but as I'm not really a K series expert, I can't advise on what it's affecting.

A possible cause could be the temperature sensor for the ecu overheating (recording too high a temperature) being in the water rail too close to the exhaust. This would give an incorrect reading when the car is stopped for a few minutes or staitionary - there are similar issues with the sender for the temperature gauge.

Caterham can supply a kit of parts to move the senders further back around the by-pass or heater hose, thereby creating a remote installation away from the exhaust. May be worth trying.

And that kit of parts can be seen here

 

I don't think it made a huge difference to my car when first fitted (std. 1.6k with std. manifold) - I fitted it for a different reason (damaged sender in the water rail) - but I'm glad it's there now that I've upgraded to a decent 4-1 manifold system which seems to cook everything quite nicely.
