I’m new here. Bought a 1999 B3000 Troy Lee edition a couple weeks ago. 141,000 miles. Third owner. Yesterday it suddenly started shaking very rough after I pulled out of driveway. Two weeks ago I changed transmission fluid and filter. Put a can of sea foam in the fuel tank. Had a small coolant leak which I pressure tested and turned out to be radiator cap. So replaced the cap and no sign of leak.
After the sudden shaking it threw a P0306 code - misfire on 6. I replaced fuel filter and today pulled the plugs and checked compression which is between 152 and 138 across all cylinders. #6 specifically was 150, so all within good range.
Next, I’ll clean intake. But beyond that, where do I look for the cause of misfire. I’m thinking either fuel or air at this point. Injector? Would another can of sea foam help? Air intake? Cam position sensor? Timing chain? Thanks in advance for replies!
