Pretty much as per title really folks, my mate has a 1989 G plate, MFI Escort XR3i cabriolet, which runs absolutly bob on when its cold, throuigh warm up to normal operating temperature, however when it gets hot, (as in hot enough to bring the fan on,) it first begins to cough andd then cuts out. Sometimes it will do it more or less as soon as the fan has been on, th other night he was showing me and it sat idling for half an hour or so, the fan came on three times, then it died.

The ignition module on the dizzy has been changed as apparently these cause trouble.

I have also heard the cold start valve can stick, but the car doesn't tick over quickly or black smoke, but would be happy to whip it off and clean it if, if anyone can point out where it is?

Chris was saying when it cuts out, if he undoes the fuel feed to the metering head, and lets the pressure off, the car will then start.

Also, when the car cuts out, the fuel pump is still runs, eliminating pump/relay i guess.

If anyone has any suggestions or had a similar problem, it'd be handy to have some advice

 

Think you may have a sausage stuck in the inlet manifold mate

 

You reckon so Boothy? If it turns out right, you're the man.
Funny enough tho mate, I wondered that meself, that possibly a sausage had got in there after he found two eggs in the fuel tank, and a slice of bacon under the spare wheel. Cooked obviously. But because it does it sometimes very its hot, and sometimes whden its very hot, i.e. its not 'regular', i think it could only be something like a cocktail sausage, you kno them little ones you get on sticks. Apparently if a Bratwurst gets stuck in there, they dont run at all.

 

mine used to do this if left idling for a while when warm. i didnt bother to sort it cause i decided to blacktop turbo it after i stripped it for resto.

But i still have the entire mfi setup so would be interested to know the cure as i plan to use it in a cheap fiesta when cab is rebuilt... Or an off road go kart frame i have...
