Title: Focus P0171
Post by: Doctor Gollum on 11 September 2016, 22:26:09

As above, starts ok cold, but gradually misfires and dies as it warms up to the point of being undriveable...

Only code is P0171.

Time to be looking for a vacuum leak.
Start it up and wiggle all of the hoses connected to the inlet system.

Not the MAF then - I'd go with vac leak then.

Cracked a plastic vac hose in the process,  but car now fixed.

Net cost, about 2p ;D

I rub it back periodically so that the bin men know which bin it is  ;D
