Trying to find out if I can test a coil pack at home?
I’m getting all 4 according to the printout. It feels normal. I can’t tell that it’s misfiring. I read on another thread that someone had the same codes as I’m getting but only one coil pack was bad and only one cylinder was actually showing a misfire but the computer was showing all four cylinders. I’m not sure it’s electrical because we drove it for over 200 miles without it throwing a code after I put in fuel injector cleaner. It’s got new fuel, new battery, new plugs. I’m still leaning towards a HPFP but I believe I’d be getting a different code and fuel injector cleaner wouldn’t affect it if the pump was going bad. I don’t think it’s all 4 injectors going bad, odd that all 4 go out at the same time. Maybe a air leak but all the boots are tight from what I can tell. I’m literally stumped and tired of dealing with it. Probably going to dealer so they can actually see what everything is doing.If you are getting a misfire code on one cylinder, you can switch that coil pack to another cylinder and see if the misfire follows it to the new cylinder.
