Can anyone tell me the above?

Having serious issues with my 3.2 and this misfire I'm having, when it happens it's like having the brakes slammed on!! It literally throws you forward! I have to come off the gas, dip the clutch and start as per normal.

Happens with no real pattern either, very irregular!

Help!!

Crank Sensor (if thats what your referring to) is normally a no start problem, or  Ive heard in some cases, Engine cut out, followed by no start. As for the slamming you foward bit, no idea, does the TC or ABS light flash up at all?

As usual, any Codes?

[P6UL K]

Nope there's no codes and no fault lights either, I've had all the issues resolved that made the dash like a Xmas tree!

ignition related..  which the ecu cant resolve..

[P6UL K]

Any thoughts then Cem?

When was the fuel filter last changed

What mods have you made to the fuel/air delivery sides?

A 3.2 ECU is intelligent enough to create cylinder misfire codes if ignition problems cause a misfire, unlike the 2.5/3.0.

Hmm, must admit any DBW potential Miss Fires even small hic up ones have always thrown a fault light, be it only briefly sometimes. when was the last time the Codes were read with a Reader?

Fuel filter was done within the last year.

Only mods are the air box and K&N filter, has had new Vx coilpacks, plugs, oil and filter in the last 3 months

Which is why I didn't say loom, as that definitely generates codes...

Another thought, is the fuel light on/less than 1/4 tank what speed are you doing when this happens? Accelerating?

Top of the red to run out is about 5 miles at full chat and fuel starvation is about the only thing which won't put a light on...

Fuel very rarely goes below 1/4 of a tank and I always try to use Shell or Esso fuels if I can.

Yes always happens under acceleration albeit light or heavy footed, I did wonder if the signal from the pedal is breaking up on route to the ECU?

Is it Oil'ed, Maf needs cleaning?

It's brand new mate, came oiled up already. I cleaned the MAF before fitting the filter but could there be a chance that the MAF is on it's way out?
