I fitted the correct specification NGK plugs about 3k miles ago and gapped them to 1.1mm. However, a severe misfire developed yesterday and the car became virtually undriveable. This all happened after a weekend of heavy-footed driving I cleaned the plugs and checked the gaps, but the problem remained. However, I changed the plugs and the misfiring disappeared.
I'm surprised by the short time that the plugs lasted and I'm wondering whether the high boost that I'm running (I peak at about 24psi and sustain about 20 psi) might be responsible. I checked the plugs and there is no sign of damage and the electrodes look a healthy colour. The DI unit is five months old
Any suggestions?
