Car intermittently will not start. At first thought it was the fuel pump. Had it replaced, problem still occurred. I had the car checked out at another service center. They say the coils need to be replaced. I also was told by another source that it also may be the camshaft sensor. I may have both replaced.

Got a diagnostic done and found an error that the "2 4 6 ignition coil" is misfiring.

Have had this problem multiple times. 4 in the past 3 years. They replace the spark plugs for around $400 and call it good. I'm thinking there is more to it than that at this point.

I have a 3.0 6 cyl LW300. Several times in past month, engine would run rough and shake when first starting up. Sometimes, when I shut it down then, re-started it, the problem was gone. Sometimes, "service engine soon" light would stay on, even though the engine ran fine. Had a shop hook it up to a diagnosis machine that should the number 6 cylinder misfired 477 times.....but the engine ran fine. They cleared the error and service engine light went out, and vehicle runs fine. Mechanic said if it happens again, he may need to replace the coil wiring.

When starting engine, the idol goes high low. Have to keep restarting or pop the hood and play with the wires kind of up near the windshield, passenger side. Engine not getting enough power. Sounds like its misfiring
