Misfire

So what do I check then?

I may be wrong, but I think that is bank 1-3-5 Coilpack. Like I say I am probably wrong.

[Martin_1962]

Plug 5 is OK

same things as last time Martin, surely?

0170 and 0173 are now old

new petrol filter
clean air filter
new Bosch MAF

And running on BP petrol not Tesco nor LPG

Detecting  misfire on at least no5

135 coil pack as well perhaps? any cracks in the plastic, swollen rusty inards? any chafing on the wiring round the back of the block? any damage to the plug or furry pins?

No cracks, can't see any chafing, plug looks fine, only happened in 3rd at full throttle after a change from second. Has 0305ed now a couple of times at full throttle highish revs on petrol

is it me or is it always (or at least quite often) the 135 bank that plays up?
might be worth tech 2ing for a closer look, maybe fueling related, swap injector over ans see if the code follows it...maybe? struggling tbh

Nearest T2 is Brackley, swapping injectors - not plenum off again!! The cut injector cables may be an issue here as once they were on I can't get them off.

Last time I had a spate of these the problem was plugs 5 and 1 were same colour and same state

i suppose if its worse on gas then spark related, if no problem on gas then petrol/injector related?

[Martin_1962]

No problem at low throttle, gas won't work on full throttle high revs, so can't test.

Basically it cuts out 5 when full throttle and high revs are used for a while, flat out accelerating has done it 3 or 4 times in the last month or so, usually when near end of 2 or going into 3.

It idles smoothly

[Martin_1962]

Could it be worth chucking some injector cleaner through?

[feeutfo]

cant do any harm, see what others say though...
