Hey, I've got a '94 Pickup with a 22RE that has about 167,000 miles on it. For the most part, it runs strong, but some days (like today) it will idle pretty low and rough. The rough idle is pretty inconsistent though, it will do it some days, then won't do it again for a week, etc.. I wanted to know if anyone has any suggestions on things I could try to do to fix it because it is a little frustrating.

Couple quick questions, have you changed or in the case of a k&n cleaned the air filter recently, tired replacing your vacuum lines and checked out your vsv's?

I have a K&N which I recently cleaned. I also cleaned out my air intake about a month ago. I just had my timing adjusted and all was well there. The plugs and rotor have been replaced within the last 2 months. I have not checked the vacuum hoses yet or replaced any of those for that matter. What is a VSV? What do I do to check that also? How much does it usually cost to get most of the vacuum hoses from the dealer. If it isn't too much? I'll probably just buy all of those and replace them just for maintanence.

As for the vacuum hoses, go to an auto parts store with one of your vacuum hoses. They are all cut to fit so pretty much all you need is a razor blade and it is alot cheeper than buying them from the dealership. The VSV's are usually electronically controlled valves found throughout your engine that connect to your vacuum hoses ( usually they are fairly small and two wires go into them). I think you should have three of them total. let me check

p.s.
VSV stands for vacuum switching valve

How can you tell when the VSV is going bad? I located them today, but I don't really know how to tell if its functioning properly. I checked the timing again today, and it was fine.

I have a 94 also. Have you changed the fuel filter? Do you have an aftermarket cam? I do in mine and that makes it idle a little ruffer than stock? I was having the same problems with mine. So I did a complete tune up. Spark plugs, wires, cap, rotor, and fuel filter. It seemed to help. Hope you figure it out.

Try checking your plug wires with a ohm meter. I had an intermediate miss once and it turned out to be 1 wire going bad. You can get individual replacements from the dealer. The factory manual has a resistance reading for each wire.

On the VSV's you should be able to take some vacuum hose and a nine volt battery to it. First blow into the VSV without a charge going into it and then try it with a charge. I can't remember if you can blow through it without a charge or not, that's how you tell when a vsv is bad.
