    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.

    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.

    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

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