Title: Could misfire be a fuel issue?
Post by: woolley11 on 18 November 2014, 20:34:30

Just wondered if a misfire on my 3.0 pfl could be fuel related.

Have changed coil pack (new Bosch) - thinking of changing plugs and HT leads but before I go to the time and expense just wondered if it could be fuel filter or something related.  :-\

Usually oil in the plug well(s)

If you're swapping plugs/HT leads you should notice oil in plug well(s) ;)  Means your cam cover gaskets gone and probably breathers blocked ;)

I would agree with the above before messing with Fuel related items on a 3.0.

Oil / water in plug wells, spark plugs, leads, diss pack all in that order.

Codes first :y

An electrical misfire should leave a trace... is the eml on?

And no mention of wet dis pack, which given the weather of late... ::)

Not on a 3.0 pfl V6 - no codes for ignition related failures ;)

Thanks guys - no elm light on.

Mostly hiccuping/missing but sometimes it drives fine - I think I'll start with ht leads then and may as well swap plugs at same time - it's coming upto 100k and I think they are the original ht leads as I pulled one of and it's a "Beru" manuf 1999.  ???
