Hi im having problems again and i hope someone can point me in the right direction! My problems is as follows : i have fault codes 272C and 272A and my mechanic changed the MAF sensor, with a second hand one! it seemed a little better but far from fixed! today i took a sensor from a working car and put it in mine and still the same so now im 99% sure its not a sensor problem! the symptoms are when im stopped with the car in D (auto box) its very jumpy or stutters! the rev counter wobbles a bit but dosnt rev up and down! also if i try to open the oil filler cap with the engine running the car cuts out!! has anyone had this or hear of this before?? any help will be great! i dont wanna go changing bits to see the results anymore as ive spent a lot already with ring seals and other things! would love a couple of months problem free now! thanks!
