so my dad gave me his '94 yota 4x4 with the 3.0 in it. it's the truck i learned to drive on, so it's kinda sentemental. well, i drove it from north carolina to georgia. i noticed it had a slight miss fire at idle, so i decided to do a general tune up. what i found shocked me, i'm surprised it made the trip. these trucks are pretty tough, or i'm real lucky! sorry for the bad quality, they're from my phone. most of the spark plugs were caked with white carbon i guess is what it was. the origional cap and rotor button were almost wore completly out. and, the k&n filter i put in 10 years ago has not been touched since!!! i broke one of the plug wires during the install, so now i need to replace those as well. then on the last plug i went to do, went to pull the wire off, it wasn't even connected!! the porcelin part of the plug had broke in two, the truck was only running on 5 cylinders. i think the truck may run a little better after this!!!!
