Evening all. i've had the fuel trim malfunction fault appear on three occasions since the following mods were done last week;
courtenay stage 4 remap.
the fault seems to appear after i have given it some beans, say when idling at traffic lights. i've had a good look around the engine bay, everything seems to be fitted ok, no leaks that i can detect. has anyone got any thoughts on this, before i get on the phone to courtenays tomorrow. i dont particularly fancy another 500 mile round trip if i can get away with it...
ps i tried some new NGK platinums today, but its still the same.
