Getting annoyed with my 855 t5 auto getting what feela like a missfire

I have changed:

Oil
Oil filter
Fuel filter
Sparks
Spark leads
Dizzy
Rotor
Coil pack
Pcv
Timing belt and all other bits
Remapped ecu
And still getting it

Any ideas anyone before I throw the thing in the bin :/

does it do it with the standard ecu in there, just to rule the new one out of the equation and is the mis-fire at random or at set revs ???

Sorry yea should have added does it with unmapped and mapped ecu and happens only on full acceleration, when driving normally feels like the revs dip slightly and regularly

crank sensor

Maf. Mine had a splutter & had everything replaced you have mate.
It wasn't throwing up any codes to do with maf, but when it was on the diagnostics you could see the maf was reading slow.
That's my suggestion anyway mate.

crank sensor

Will give that a try cheers

so it feels like the power is surging as you go up though the rev range ??

i'd say crank sensor also, my peugeot was doing the same thing the other day, put a code reader on it (a proper one) and it was crank sensor

All sorted now put new crank and cam sensor on, took mbc off and running off the bcs with new silicone hoses its boosting really well with no fluctuations or anything

Thanks a lot guys :)

[AndysR]

Always nice to fix a fault and enjoy your car again :)

[daza-b]

Gotta go get fuel so get to give it a good test hehe :)

Same here,also have you changed all the vacuum lines cos u might have a leak somewhere too

[Biff]

Happy days mate glad you sorted it. :)

[T5frankie]

crank sensor faults often only show up on full acceleration,

Yeah all hoses were changed awhile ago
