Hi Guys,
The Mini has just developed a cold starting issue - when starting the engine when it's cold, it seems to take a while to start/spark (it turns over pretty quickly), once it's sparked it seems to splutter and then die (as if it's running on a couple of cylinders). After a couple of attempts I am finally able to keep it going long enough (whilst running roughly) to feather the throttle without stalling it and once the revs build up it starts running on all 4 cylinders and then after that it's absolutely fine??
I've checked all the obvious things - battery terminals, new negative battery earth cable and engine earth strap, clean spark plugs, ht leads, distributor cap and rotor arm.
After that initial cold start the Mini will be absolutely fine for the rest of the day.
Could it be something to do with the starter motor or the ignition coil? If so how would I test them?
Many thanks your time guys! Mike
P.S, it's a 1989 Mini Mayfair, with electronic ignition
