any dexron III will do atf

to add its sooo hard to tell without seeing it as could be a air flow meter issue or a lambda sensor,allsorts. start with the plugs which is a obvious service item

have you checked the spark plugs/ coil packs?? maybe unrelated to the fuel, cars love throwing you off the scent!

any reason why i shouldn't use 10w 40 semi synthetic in my x type with 168 thousand on the clock. figured it could use a slightly thicker lube as its bound to be a bit worn!!!?
