Spark Plug changed, now this!?
So I replaced my spark plugs yesterday because the ones in the truck were the original ones 110,000 miles ago. 4 of them came out easy, and 2 of them gave me a bunch of trouble. The new ones would only go in halfway, so I backed them out, and yep... cross-threaded. I was in a huge hurry, so I took it to the stealership to have them get them in. Turns out they had to re-tap the block. Got the new plugs in. It started up great and I went home $240 later.
Now, I go start my truck after it sat cold for awhile. It took about 5 seconds to turn over. Once it started, it seems to run smooth. No shaking or anything. I just put in a new battery with high cold-cranking amps about a month ago. Also just did a new synthetic oil change last week.
It seems when the truck is hot, it turns over just fine, but when it's cold, it sounds horrible and takes forever to turn over. I will keep an eye on my gas mileage this week. Maybe a spark plug is misfiring lightly.
