Ok I thought I would run the engine up to temps. While I was doing that I gave the Maf plug a wiggle and it stalled the engine.
I had this some time ago and re taped up the plug after cleaning and checking.
Anyway I restarted the car and continued to run it up to temps,minutes later I got interrupted by a neighbour and had to switch the engine off.
5 mins later I've started it and the injector light blipped off and then back on, then it went off completely.
Everything back to normal!
