Sounds stilly but my car idles crap if you start it with your foot on the throttle. I have to discount the battery for a couple mins and then it runs fine.

My 2.0 HDi ran around with a shot MAF without me knowing (so probably equivalent to when you unplug yours)
During extra 30bhp remap pro_steve from HDI-tuning said that I have to get that sorted, as map needs it.
He said car was driving fine because ECU comes up with failsafe default values, and it's perfectly OK for emissions with factory's engine tune and in this climate.
So why can't you just pass your MOT with MAF unplugged? All my MOTs were in January, pass with flying colours seemingly with shot MAF too

If the engine management light is on, it will fail.
woody1982-1: fit a new MAF ?
