Title: Misfire after cam cover and thermostat change (2.5 V6)
Post by: steve6367 on 01 August 2014, 14:54:29

Finished the above, which took much longer than I thought only to find its misfiring. No lights of codes logged but definitely misfiring. I've checked and triple checked I've not left anything disconnected and plug leads are on the correct plugs.

Anything I should be looking for? (HT leads and plugs are new as the old ones were oil soaked)

Many thanks

Steve

Yes, make sure the HT leads to the DIS pack on the 2-4-6 bank are correct as its not obvious (and as logical as you would think)

Definitely would be checking again that you got the ht leads in the right order and on the right pot.

Everything plugged back in on the fuel rail? No injectors accidentally unplugged?

Thank you - I did the plug cables by labelling before disconnect so if I got that wrong then they could be wrong. Is there a method to know where they should be? I can't see any labelling on the dis pack.

Number 6 lead is short and can be pulled off the diss pac when removing it from the plug hole ::)
