My truck recently had a massive MPG drop - from almost 17MPG down to
just a tad over 13mpg, and I was noticing today that it's lacking in
power too - used to practically create g-forces when I accelerate, now
it's decidedly sluggish.
I'd written off the mpg change to the Opal gas we're forced to use in
our vehicles here in central Australia (don't get me started -grr- but
in short Opal is unsniffable. It also destroys engines built before
about 1986 but is *supposed*
to be safe for newer vehicles)
Anyway, someone told me it could just be that I have a fouled spark.
Quite possible, haven't touched the sparks since I got the vehicle (for
those who don't know me: 2001 Dakota 4x4 4.7l v8).
Is that the most likely reason? Is there anything else I should be
looking at? I don't have a spark puller, so I'll likely drop it off at
the mechanic's. I needed to take it in anyway, for PM before we go on
our massive quasi-4x4 odyssey across the Australian Outback to the coast.
Thanks, as always, for any advice.
