OK...

I have spent a lot of money and a lot of time doing all this work to my car and my mileage hasn't improved at ALL.

I filled up today with plus 89 gas...I had 155.3 miles on this tank and I filled up with 13.943 gallons. That comes to 11.138 MPG

I don't know what to do next...maybe get my injectors cleaned? I mean I have spent over 200 bucks tuning this thing up to improve mileage and NOTHING. How much more do I have to put in it???

ANY and ALL suggestions are welcome!!

I've lost track of your previous thread(s), so please pardon me for asking questions that you may have already answered.

• What are your driving habits like? How heavy is your right foot?
• Describe your daily drive to/from work. Length, time of day, amount of stop and go traffic...
• Do you have access to any diag tools that can give you either a readout of the votage at the front O2 sensor?
• How does the engine run in general? Does it bog off the line?
• What engine is in the truck?
• What's the best mileage that you've ever gotten? When's the last time that you remember getting something like it?
• What's the last _major_ powertrain work you had done on the truck? (tranny, CV joints, transfer case, either diff, etc.)
• Is Fayetteville flat, hilly, mountainous? Any idea of your elevation?

I think that's all I can come up with at the moment...

Maybe it's all of those damn hills in Fayetteville!

I would check to see if maybe your cat is clogged. I'm not sure exactly what you've done, but when i traded in my '91, it was getting about the same mileage you are getting, but it was only firing 5 cyls.

Are you running larger tires than you are geared for, that makes a HUGE difference in miles for sure.
