Spark Plugs!
Well its been running
a little rough for the last month, maybe longer but steadily getting
worse, most noticably if I change up too early at low revs, it was
misfiring, stuttering until the revs picked up and then it smoothed
out
so today I bought some new plugs to see if I could cure the problem
new vs old click for large
version
Perhaps I should have took a pic against a better background to make
it clearer to see, but looking closely the old plug has really worn
out, and the gap really wide compared to the pre-gapped new plug on
the left
I think that the fuel/air mix at low rpm/high load has possibly
wiped out the flame so to speak, resulting in the symptoms described
A quick test run of local roads featuring a country lane, up a hill,
then some duel carriageway up and downhill and level, and nice
smooth service is now resumed!!!
I kick myself now at how much fuel I may have wasted over the time
its had a problem, all for the sake of a fiver on some new plugs
The plugs I removed I estimate to have done around 40,000 miles in
my ownership.
