TonyAngel said:I just wanted to update. Fuel mileage seems to have stabilized at around 15, give or take 1 or 2. Not great, but better than the 11 is was getting. I did a bit of research on my tires and it turns out that I had them really under inflated. Doing the chalk test, I settled on 50 psi for the "E" load rated tires. Handling tightened up and that vibration I was getting at highway speeds went away.
In the end the plugs, oil and air pressure put my mileage where I should be.
TonyAngel said:No way I could keep the tach under 1500. I'd get run over by a Prius. Driving like I normally do, it usually stay at 2500 or under. When merging, it gets whatever it takes.

I always thank Prius drivers for saving gas for my Avalanche.Wickman said:I love Priuses, they make for good traction.
i have a 03 with 140k and a friend has a 03 with 200k. We both have original pugs.TonyAngel said:Before I go shooting in the dark, I think I'll go with the most obvious and change the plugs. Taking a closer look under the hood, I don't think they've been changed since new. I only have 57K miles on it, but the idle isn't as smooth and I think it should be. Probably do the wires too.
