V6 intermittent misfire
Car is a 1999 GTV V6 - ran for the first time in a couple of months after refitting interior following a leather restore.
Ran perfectly yesterday, gave it a good clean including under the bonnet, kept engine running and was careful in terms of cleaning.
Ran perfectly this afternoon then suddenly developed a misfire. Unplugged the MAF and was still present - MAF was only changed just before Christmas so I'm confident its not that.
No warning lights.
Should the next step be to replace plugs - or should I suspect a coil?
