Hi, last week my check engine light came on, gave me a code 43. Since there are like 8 options for this code, I took it to a friend with a scanner. The codes came back as a multiple cylinder misfire on cylinders 1 and 6. His suggestion was to replace the plugs and the wires and that would hopefully fix the problem. Last night, I replaced the plugs and the wires. I had disconnected the battery to clear the code so when I started it up the first time, it was a little rough (not too bad though). After I drove it for about 5 minutes it was running smooth and felt great. There was no hesitation or anything like what I had been experiencing before. This morning I went out to warm it up before I came to work, and when I got in to leave, the light was on again. I've again checked the code, and it says code 43.
