Latest update on my ill car...
As you can guess the car messed up again last night in the middle of rush hour traffic, :embarassed: but unlike usual where i switch off the ignition and switch it back onto clear the fault, it wouldn't re-start.

The starter motor was turning over ok, but the engine would not fire (no 'chugging' as if it was trying to turn over) and the oil light began to flash...
AA to the rescue!
Called out the men in yellow. He diagnosed the problem within 2min saying he'd seen it before. The spark plugs weren't firing. He put some fancy machine on the distributer and had it running in minutes. He said it was a
fauty regulator on the back of the coil. By stroke of luck he had the exact part in the back of the van. Unfortunately you cant buy it separately as it come as part of the coil assembly. ?87 and 5 minutes later the car was running again.
Hopefully this will have cured my problem. He said that the intermittent fault wouldn't show up on a computer because it doesn't occur when the car is warm, which ties in with my problems only occurring within the 1st 5 minutes of driving.
Dont know if you guys have change this part yet? May be worth a try?
