howdy yall its been a while since ive been on here. but i havent left for good yet. Since my last visit i have hit 100000 miles on my dodge and its starting to show. my v6 is gettin 12mpg which i know is close to what it should good. its time to do a tune up, plugs wires, fuel filter. Im here to ask what brands and what else do yall think i should do for the tune up? i got a new job which involves me driving at LEAST 50 miles a day so if i could, at all possible, raise my mileage that would be awesome. i was planning on getting a new truck but that wont happen so i wanna make mine a little better. been thinking about wheels and tires and i wanna go to 33" which i know wont help a bit in the fuel department. and before someone says "why put big tires on a 2wd?" my truck is barely worth $2000 where i live so i might as well have fun with it and make it more enjoyable for me.

side note i stumbled upon this video on youtube. and im 99% sure this dude is lieing about his gas mileage cause he advertises his v6 ram on 35"s getting 15-17 mpg. what are yalls thoughts? here is the video

Lotta folks like the Accel kits. Comes with plugs, wires, cap, and rotor. (all of which should be changed for a 'tune up'.) Also PCV valve. Get one from the dealer, the aftermarket guys don't always have the correct flow rate. Fuel filter isn't really user-serviceable. It's IN the tank....... (brilliant idea there dodge......) There are comes threads in the faq section on the 'popular' plugs, wires, and such. Just regular ol' copper plugs seem to work better in these engines.

If you buy parts individually, get a cap with brass terminals, a GOOD set of wires.

Probably time for O2 sensors as well. (NTK, or Denso, stay away from Bosch.) When you have everything changed out, disconnect the battery for a few minutes to reset the PCM, and let it re-learn how to run the engine with the new parts.

 

well as you can tell ive never done this ha. pcv?? and what all goes into out o2 sensor(s)? i thought i just had one in the cat? is it as simple as unplug replace and replug?

 

PCV=Postive Crankcase Ventilation. I yours, I think the valve is in the drivers side valve cover? It will have a vacuum line going to the manifold itself. It's like 8 bucks from the dealer.

You probably have two O2 sensors, one Pre-cat, and one Post-cat. Post-cat you can probably leave in. Pre-cat is the one that the PCM depends on the most. Its in the exhaust.... hanging out UNDER the truck..... so, convincing them to come of can sometimes be 'fun'...... But yes, it is just that easy. Unplug the connector, unscrew the sensor, screw in the new one, plug it in. All done.

 

Yes, my pcv is on driver's side. Seems to be the change in our year.

I only have 1 pre, and 1 post O2 sensor. May or may not be same for OP depending on exhaust changes right?

Here is view of my pre and post sensors, respectively:
