Hi
When servicing my Rover 25, I got seduced by the blurb surrounding 4 electrode SPs and decided to fit some.
The starting had gradually become more problematic, eventually taking a couple of turns of the key each time, to successfully start.
Initially I changed the fuel filter, knowing it hadn't been done, but then reverted to a new set of the correct plugs when that made no difference.
The next morning the starting was just as hesistant but since then it has been fine.
My question is, could this initial problem have been caused by the ECU re-adjusting it's settings or am I assuming an early ECU is far too clever ? I'm just interested why there might have been this initial delay in reverting to normal starting.
FWIW I came across this on the
