So after having serious problems with a miss fire under load and lots of flat spots and spending lots of money on new timing belts aux map sensor lambda sensor etc etc and it still not running right, i decided to start unplugging all these new sensors because why not!!!....what harm could it do considering i just spent close to 800 quidd on this french piece of s**t and its worse off now than how it was before. i got to the MAP sensor unhooked it and the car runs like a dream no problems no miss fires good mpg, pulls like the clappers and makes me smile again... i plug it back in again tonight to see if its still playing up and sure enough pop pop bang bang misfiring all the way through! any idea????
