Hi folks,

My plan is to get the car in for a good set up in new year, which should hopefully cure the following, however was curious if anyone had any ideas.

When started from stone cold, the car will run very lumpy and almost on 3 cylinders. It will run badly for a few seconds then cut out. Start again and does the same thing, after a few seconds it will take a rev (sometimes cuts out when you try and rev it) then settles into a perfect idle on all four cylinders.

Starts perfectly when hot so was thinking it may be something like a sensor? Blue coolant sensor at rear perhaps?

Its stage 3 running gear, still on a dizzy at the moment. Running a group A coil as well.

sounds like a damp engine..

I would go threw all the sensors multiplugs , compress the pins so they grip the sensors tight and put a tab of patrolluim jelly to prevent corrosion/mouisture ingress ;)

Thanks guys, changed the blue sensor (what a pig to get at) and car seems a lot happier at cold starts!

Still to get a good check over and set up, but I'm happy with that.
