My US spec '86 Turbo fires up first time but runs very very rich and smokes like a bastard until it warms up a bit. (A couple of minutes if you leave it idling, shorter if you drive away) Clears before it reaches normal temperature. Once it's hot runs fine, albeit a little rich at idle with no smoke. It has an Autothority MAF and chips installed.
Any common failures on the 951 I should be checking for?
Cheers.

Temp sensor at the front of the block Michael I think

Got the same issue with the 968, massive over fuelling at startup

Yeah that was my first thought, will have to measure the resistance and see if it's within spec.
