Fixed the misfire code, cylinder #6 plug was the culprit once again. These were only 3 years old. Put hotter plugs in. Going in for state inspection/emissions testing tomorrow.

You didn’t happen to buy those AC Delco plugs for 1/4 the going rate did you? There’s been some counterfeits being sold that don’t last long.

I'm an idiot.

I changed my oil on sunday, and...I'm just realizing now...I put in the wrong oil. :emotions122:

Calls for 5w-30, I used 5w-20. Not a huge deal..... I'll run it until it gets super cold, but I really dont know why that 5w20 is still stuck in my head. I used to use it on my explorer that I had for quite some years...I dunno, but it dawned on me today while I was getting gas. Popped the hood, 5w30 on the filler cap.....5w20 on the spare/excess bottle I keep in the back seat. Dammit.

I got a set of NGK marine plugs off of ebay a few years ago.
they didn't quite look right.. a little rough.
The engine wouldn't run, drove me nuts until i put the old plugs back in.
fired right up.

I now only like to buy plugs from known good retailers.
some of the newer counterfeits look really good, early on they were much easier to tell.

I did this once a few years ago. Didn’t realize it until I was pouring the old oil into the jug for the next time I made a used fluid run. I was so pissed off that I went and bought six more qts and a new filter and changed the oil again. Probably could have gotten by, but I had just swapped out a cam due to a lifter locking up. Must have grabbed the wrong stuff off the shelf as I was in a little bit of a hurry when I picked it up.

Well, my oil pressure was a hair lower than usual lately...not drastic, just a tick lower. I was like hmmmm..wonder whats going on here. I use 5 qts and a quart of MMO. It's a cocktail I feel works well for me, and sure enough its 5w20....grr.
