This goes for any kind of maintenance. Car, house, etc...
You can buy a Craftsman or Snap-On ratchet and never have to buy a ratchet again for the rest of your life. Or you can get the cheap crap at K-Mart and replace it every six month. The good stuff costs more up front, but by the time you get 10 years down the road it will have saved you money.
Being cheap is expensive.

Also mention to them to check out the IAT sensor. It is the Intake Air Temperature sensor and calculates estimated air mass by the temperature and if it's messed up it could be telling your PCM you got ice cold air in the intake and it think it had a lot of mass, however its really 92* air going in with lower mass.
It will cause it to literally dump gasoline and will cause it to run very rich.
I forget what engine you have but you have a '98 so either 5.2 or 5.9 it should look about the same. Here's a customers 5.9 (I have a custom intake manifold so different area) and I circled the IAT sensor:

Usually my redneck repairs get the job done cheap, but when it comes to eletrical touchy sensors that's where I don't mess around. My toolbox is filled with cheap junk tools that I just collected from random places and I swear half of them came out of a cereal box or something haha.
Good call on the IAT widow. That might be something I'd just go ahead and replace anyways for peace of mind, if it's cheap enough. I miss the days when the carb float was all the sensors you'd ever need in your engine, and that one never went bad either and only costed like $2.

Ahh yes! I can't tell you how many times a can of WD-40 saved me. Actually more recently last summer I had my A/C compressor about seize up on me, just sprayed some WD-40 into the backside of the pulley and front side by the bolts and made it another 32 miles back to my shop!
Miracle if you ask me seeing as the truck wouldn't even turn over because it was almost completely seized!
