my rs will start no bother, idle no bother and if i take the revs up slowly go all the way up and if i am hard on the throttle it pops, bangs, backfires and generally wont rev.

ive changed the plugs and they were very sooted up
changed the coil pack and leads as i thought the coil pack was breaking down under load but no joy

its not smokey but does have a strong petrol smell coming out the rs end

any ideas?

Quite keen to see people thoughts on this to, as mine does the same!

frsjon

throttle position sensor would be my first thing to check after what you have changed already..

Joe-FRST

I am going to try crank sensor?

frsjon

if the crank sensor wasnt working you wouldnt have any fuel or spark. if you have a spare then no harm in swapping them to check

Joe-FRST

That's true :/

frsjon

if it was doing this once warm another one to check would be the coolant temp sensor but i take it these problems are from cold.

Joe-FRST

My issue is warm! I have a custom temp sensor.

Running 235 bhp so I might try upgrading injectors! They might be on the limit?

frsjon

what ecu are you using joe?

Joe-FRST

Standard :/

frsjon

why the custom temp sensor? you sure your not thinking temp sender? any way best thing mate would be to get it on the rollers,will find out pretty quickly what the issue is

Joe-FRST

Sorry, it's a temp sendor to a gauge.

Yeah I was thing of getting a omex 600 and taking it down to Motorsport developments to remap it.

Not sure how much they charge though :/
