Spark plugs failed on me again this weekend, was suck in a huge traffic jam for almost an hour/moving alittle no more than 5mph 1st gear.
Its the 3rd time this year they have gone, all when stuck in traffic for a long time.
The engine warning light comes on, kind of goes in to a limp mode but this weekend I noticed a bit of smoke coming out of the exhaust shortly before it happened.
Got the aa out and they confirmed spark plug 3 had a misfire, he took a look and saw it had a coating of oil on it, cleaned it up and now its running smoothly again. He thinks I may have had a faulty ignition coil installed a few months back.
Before I take it to the garage anyone shed any light on this and back up aa theory? its coming up to MOT time and tbh if its a huge expensive job I’m thinking of getting its through its MOT and part ex, its starting to get a lot of problems recently, wiper motor gone, igniton cylinder replacing, power steering went, all sorted now but this engine one is causing me the most concern.
