have had problems now for some time have had new sensor, new air filter, plugs, checked cam, checked air system for leaks, car has gone into auto electrical engineers and they are stumped, runs like a dream without the sensor plugged in, but as soon as the codes are cleared and its re plugged car acts like a nutter, wont pull, wont excellerate, trying to hold at speed and you feel surges and dying, at times the tick over is erratic, and at worst it will refuse to pull just as you try to come out of a junction, am running it at the mo without sensor plugged in but obviously this is not really a good idea for too long, engine code is po100 so its def a maf problem, so HELP !!!!!
