A nice Christmas present for me - my wagon limped home after a long towing effort . It's happened twice now - brand new plugs and runs ok, then after about a 3 hour drive under load ( car trailer ), the car backfires and seems to drop a cylinder or two. I pulled the plugs out and the ceramic on 4 out of 6 plugs was cracked - they were brand new this time! So not sure whether the gas backfire caused the plugs to crack or the other way around. Any ideas? I'm using NGK BPR6EF-13 plugs and they seem to be gapped at about 1.3. This morning I scraped together some old plugs that weren't cracked and regapped them to 1.5 to see if it would run on petrol - still misfiring. I've had constant problems with LPG and poor fuel economy so I think I will just try and get the car running back on Petrol now. Which plugs should I buy for standard petrol?
Thanks in advance and merry christmas
