hi im currently working on my friends civic coupe d17 uk spec
and it came in with a very wierd problem
its idle;s fine but wont accelerate under load
ive had the injectors tested and cleaned
new plugs
new fuel pump
ive checked the cat
ive had it under snap on diognostics
and it came back with something to do with cat or lamba sensor
not put new lamba sensors in yet

checked the coils with a new set

the problem was even worse before you couldnt drive the car anywere under full throttle meaning setting off was nt happening

now it seems to rev once to redline then next time it'dd just die and may even die completly

any ideas would be much apprecitiated
