Toyota! (and Lexus and Scion) / 20r engine 13 MPG?!?!
« on: March 10, 2007, 12:36:56 AM »
My 79 toyota pickup is costing me too much for gas.  I don\'t use it much but when I do, I know I\'ll have to be willing to pay through the nose!

Here are the symptoms:

1. The air filter gets clogged really quickly with a black soot.
2. It backfires and puffs out a little cloud when I shift from first to second.  Sometimes it does this when shifting in the other gears.  Sometimes it backfires when I back off the gas.
3. It gets really bad gas mileage.  I was hoping for at least 20 MPG.

Other than this it runs pretty good!

I\'d say it sounds like it is running rich but I couldn\'t find a mixture adjustment in the Chilton\'s manual.  All I could find was a backfire valve.

I\'ve already replaced the plugs, wires, and even the distributor (my son knew of a junker celica with a 20r).

Any suggestions?
