Kind of makes me miss the days when all you had to do was pull a plug, have someone turn the engine over once or twice and see if there was a spark in the spark plug.

Well, that seems like a good idea. I'll start doing that once I get the boat seaworthy again.Could be because i come from a gx470 background, but I use 4lo at least once a month to make sure it stays working. Same with the center diff lock. Use it or lose it they always say right?

Misfire codes can be caused by many things, even stuff like vacuum leaks in the intake.

You may need a better test. My battery did the same thing but was still a defective battery after having it bench tested at the dealer. Same thing with my alternator. Would be a good idea to have the battery bench tested at autozone, oreilly or the dealer.Easy enough to check. With truck off, I get 12.45V across the posts. With it running at idle I get 13.95V, so it would seem that alternator is good.
i think if the maf is plugged in it wouldn’t throw any other codesIf I pop off the air filter housing to get to the coils, shouldn't I expect a bunch of codes to throw when I start the engine to test if the problem followed the coil? I don't have to button the air filter housing and hoses all back up before doing that test do I?

took me many extensions and bad words to get those bad boys outOhm meter reads consistent values across blades 1 and 4 of coil #2 and coil #4. So while that doesn't rule the coil out, it makes it a lot less likely, doesn't it? Time to pull the spark plug, will run grab a new one first since I am in here.
How you would get to coil #6 and especially #8 must be magic, but thank goodness those aren't the concern.
I will go ahead and elevate you and guys like you up to god status.took me many extensions and bad words to get those bad boys out
i think normally any cel light needs a few miles to relearn to see if code is still present best bet would be to clear and see if it comes backI swapped it. I couldn't not swap it. If the problem went away would the 4LO light go off when I start the car, or would I need to clear it and see if it came back? Because it didn't just go away which means the problem is still there or I need to clear it. So I am going to read it before I clear it, then if nothing is different I am going to clear it.
Ah, interesting. Well, I cleared it and took it to a nearby car wash, cleaned it, then drove home with no lights. Fingers crossed it stays that way. Coincidentally my routine oil change is due tomorrow so I will get a quote to change the other 6 plugs.i think normally any cel light needs a few miles to relearn to see if code is still present best bet would be to clear and see if it comes back
Good, I was hoping to get some opinions on it. It's kinds charred on one side and you can see the other side pretty well. Seems fouled, but I don't speak spark plug. I will say the #2 spark plug was less nasty looking for sure in comparison.That plug looks wet, not firing. Hopefully just a plug and/or coil
I took my time on a Saturday and was about 2 hours to replace all spark plugs. Tools make all the difference
