It's on a factory map. I've had long term wet running issues, as a result of which I have changed HT leads and caps multiple times. Running NGK . Wet issues seem to be solved now - sealant round ECU plugs. I'm reluctant to change her leads and caps again - yet again! - but I could. Running a Termignoni silencer, but that has been on from the outset. No recent mods
Where do I start, do you think? She's an older 8v, which I bought new in 2008. Has about 60k miles.
