1991 Toyota Camry getting horrible gas mileage

[ja23merz]

So I have a camry and everything runs fine. The only problem is that it's getting 20mpg when it should be getting 30ish mpg. I've done the usual maintenance items such as rotor, cap, wires, plugs, fuel filter, and air filter. The throttle body has been cleaned and the tires have been inflated to the recommended psi. I've even tried running injector cleaner through the fuel system, but nothing has improved.

What could be the problem? The car has 70k miles and is in pretty top notch condition. Any suggestions are welcome.

any cels? 5sfe or is it the v6? if anything it might be your MAF, o2 sensors, ECT, or you have dragging(sticking) brakes. clean your TB out and check your timing.

burn any oil? compression test? alignment? brakes dragging?

It is the 4cyl model. Theres no CEL and also the brakes aren't dragging. However, the car pulls slightly to the right when driving, but that can't be the sole reason for the horrible gas mileage. I, too, was thinking the 02 sensor, but I wanted to rule out other possibilities first. No signs of burning oil and the timing is spot on. I forgot if the car had a MAF. If it does, how can I tell if mine is bad? What's the ECT?

cat could be clogged or egr. worked on a 97 camery and the egr was bad ran horrible gas milage.

i would say an auto version would get mid 20's not 30 mpg. is ur car an auto? or a 5 spd?
