Poxy Misfire on the 3.2
« on: 10 May 2014, 23:10:20 »
Evening guys,

Have replaced the coilpacks with brand new Bosch items and the misfire still remains! Very infuriating! Will check the codes in the morning via the pedal
But could there be something else causing this?

CPS? Cam sensor?

Seems to happen under load rather than light acceleration.

*Edit...

Just had recent mini-service using new Vx oil/filter/plugs etc...

Plugs holes were free of oil and water, bone dry in fact!

Two words...

Engine Loom.

That was the only thing that cured mine. If you can get one, a low mileage 2.6 manual loom is your best bet :y

Done the pedal test and I'm getting P1111...

P1111 Intake Manifold Valve 2 Voltage High
P1111 Intake Manifold Valve 2 Voltage Low
P1111 Intake Manifold Valve 2 Open

Now, what can that mean? Double Dutch to me :-[

Means there's a multi ram not working. Guessing plug is off at the back of the plenum.


Although I'm not sure which is 1 and which is 2...?

Cheers Chris, cant be that then as the issue has been going for a while long since the dual ram removal.... Took the car for a good run and it disappeared but my luck was short lived as once the car got to hot it returned and made the car pop and bang!

You couldn't be any further from the truth! Just goes to show that the vacuum system and any/all the mods I've done have no effect on the engine running  :P :-X :D ;D
