So, I've got a big update --
I replaced my fan clutch and cleaned my MAF sensor and air filter yesterday. It feels like a completely different truck!
Also, while doing such, my mom came out and was talking to me, and she gave me an offer I'm having an extremely hard time refusing.
She brought up a point that I bought the truck for carrying my drums, which she's right. However, she also made a good argument -- If I have my drums in the bed of the truck and it's raining, that's a problem. If I have my drums in the back of the truck while out and about and I have to make a stop, that's a $1,300 target.
So, she's encouraging me to trade my truck since it's running well now. I've tested it -- this thing hauls now!
She also said that if I couldn't trade it, she'd consider BUYING my next vehicle and then I'd pay her back when I sell the truck. So, I'm currently looking at a '97 CR-V and a '02 Blazer. We'll see what happens.
