I also went down this path. I actually got it working decently but ... with the bridge plugged in my garage door opens on it's own randomly every couple of days. No pattern to it ... 3am in the morning or middle of the day. Obviously I can't have it just randomly open and leave my house...
In my brain I was thinking that the carbon would settle in the pan, but you are right, it should get all mixed up into the mysterious unknown where the bottom of the dipstick sits too, so that will be a lot easier to check.
Interesting. I literally just changed it right _before_ adding the fuel system cleaner. I had my 5,000 mile service, brought it home, drove it about 30 miles until the lights came on, added enough gas to get it to half a tank, then added the fuel injector cleaner. Still think I think I...
So the fuel injectors seem complicated to get to, and I didn't want to dive that far in if I don't have to. When I pulled the spark plug, it was fouled, and visually looking inside the spark plug socket with a strong light I could see carbon (had the color of a cast iron pan).
Since the...
No, it looks really complicated to get to the fuel injectors in this bad boy. I'm a bit concerned with tearing it that far apart myself. I will say when I pulled the spark plug the engine looked pretty dirty down in the port, I am thinking about starting with running some fuel injector...
Seems to me either your MAP sensor is faulty or the wiring to the MAP sensor is faulty.
If it were me, I disconnect the sensor connector which seems super easy to get to and check the voltages per the FSM:
E2 is ground, so with the engine on, I would check voltage across ...
pin 1 and 2 for...
Yeah crazy coincidence if not related. You double checked all of the items that you disconnected, that you reconnected them properly and didnt leave something loose or forget one?
