it idles, but is very irratic, kinda like its going to stall and its fighting to keep running, putting foot on pedal makes it smooth out but after that at idle it tends to get worse and hunts for a idle again...

i have fitted 2l maf, trottle body, new followers and cams...

could the cams be making it run ruggid

it has a tapping noise when running, not sure if its the new followers bedding in as i drove it 4 miles and didnt shut up.. lol

when driving its awsome, pulls like a train and sounds nice with the scorpion exhaust, well under the tapping noise at the top end, like you say with air leak i'll swap out the injectors and double check all bolts around inlet

what ECU should i be running? i do have another code 2fdc i think... its something like that would that be the one to use????

lambda is new as is cat, cam sensor, crank sensor replaced with no difference.

going to get a new fuel filter as i feel its in need of a new one
