bad mileage
Hey folk, new posting here. You ugy got tons of good info out there.
So here is what I got, 94 xtra cab with a 3.0, the mileage went way down from last year and it has been running kinda rough especially at idle. I took the plugs out and they had normal wear on them and all that but I cleaned them anyway. Occasionally I get a miss during running as well. What do you guys think?

take a look at your air filter, clean your MAF..
i wouldnt have pulled the plugs and cleaned em either, you shoulda just replaced with new...infact, with what you said i would prolly do a full tune up, sounds like its about that time...

The air filter is less than a year old, 02 sensor well I dunno lol, fuel filter is 3 months old, pcv valve the same.
I don't ilke the wires on my truck either, they are these little tiny flimsy looking things. They have performance sets out there but I have only been able to find the real expensive ones.
What plugs you guys running?

I am getting about 14 highway and less in the city, the fuel filter is less than a year, air filter less than a year along with the pcv. The stock wires are wimpy but they are expensive. What plugs and wires you guys running?

I had the same problem, did everything with no luck. Turned out that the miss would come and go. One day the miss came, and never went away. Turned out to be a bad exhust valve.

Use NGK or Denso plugs.
Did anything unusual happen when your mileage went down? Have you made any changes to the truck? New tires? Steering recall? Was it sudden or over a period of time? More questions need to be asked/answered before everyone has you throw money at it.

By the time you get done with a 3.4 mod you could potentially have $5k in it (some have)...just FYI. Like dijlop said, it depends on your mechanic skills & ability to find stuff on the cheap.
