hey guys i seriously need help as this problem has been drivin me mad for about 7months this is a temporary thing that comes and goes ..

Basicaly my engine light is on and could drive like ther was no problem for a while, but then what happens is i found that when stationary the car sometimes judders and the revs go all over the place and then the engine cuts out. to keep it goin i have to realy keep the revs high by pushin the acceleratar to the floor.

ive been to a ton of garages including MAIN DEALER with them all sayin they basicaly dont know??? and spent alot of money tryin to resolve this

with all my attemps at the garages ive had diognostics read and they all say ...

SYSTEM RUNNING TO LEAN BANK 1 AND SYSTEM RUNNING TO LEAN BANK 2

would really really apreciate if anybody can help

thanks

If manifold was not tight or gasket was suspect , could draw air causing lean setting ?Could also check any vacuum pipes / hoses for fitment or leaks .

im just waitin for the problem to occur again as its a temprement thing but as i say the engine light is still on

check your o2 sensor readings on a diagnostic machine,it could be that one of your sensors is faulty,also check your cat is`nt blocked or the element broken up inside,check the readings from your engine sensors on live data and make sure readings are within spec
