Hi, I have recently started having a problem with my Cav GSI... It starts fine when cold and causes no problems but after a short journey, if left for 15 mins-2.5 hours, when restarted it misfires and doesn't idle properly at all. You can rev it but have diffichulty pulling away as it nearly cuts out. If you rev it to 3000 then pull away it seems to sort it out and it will be ok until you stop again. I have changed the temp sensor in thr thermostat housing and I also replaced the vacuum hose to the fuel regulator valve in case it was split and causing probs.
Anyone have any other ideas as to the cause?
