Well new to me that is...Hey everyone newbie here looking for some input. I just bought a 89 2wd p/u with the carb'd 22r. The truck was getting horrible mileage...12-13 on the fwy. After reading some stuff here I narowed it down to a combination of the carb aap valve and a stuck thermostat. After repairing(plugged the vac lines on the aap, replaced thermostat) those items as well as a complete tune up I got 26 all fwy and 20 ALL city. I drive the truck very nicely and save my lead foot for the other truck. My question is, is that about as good as it gets? Ive checked the pcv valve, seems to be functioning properly, im pretty sure the original cat is on there but it passes smog no problem, timing is dead on 0 and 12 (I actually just put another 5* advance into it to see what that does)...ive read up on the egr but havent removed it yet to check it. The truck runs flawlessly even in the idaho winter weather. So anyone got any tips for me, things to check, swap out. I have no problem putting some cash into the truck if it will help out! Thanks in advance for your time and help...you guys have helped me out a ton already! Mike

 

My truck with 31" mud tires seems to get about 17 on the highway and up to 25 in the city, I know that is backwards to normal but I think it might be because I need to give it so much throttle just to stay at or above 60 mph, not a lot of balls in the RustRunner

 

People always claim higher mpg than they get, just like their horsepower, but IMO, that's about as good as it's going to get for you with a carb. I get 17 mixed with a weber and 4:88 gears, 33" tires.

 

yeah, i would stick with that. you should be happy!!!

im getting 13.5 city with 31's!!!!

 

Is that 2wd or 4wd trucK?

 

Ive gotten 30 mpgs in my 81 4x4 carb, usually about 25 highway and 20 city. My buddys 2wd 22r gets 30 mpgs constantly.

 

30 mpg constantly?...I now have mpg envy.....IM gonna fill up tomorrow so ill post in a week or so what my repairs/adjustments did if anything. Being winter time and letting the truck warm up every morning is definetely gonna hurt my average as well as the crap fuel we get..not to mention when the roads are slick its kinda tough not to have some fun...
