Help 95 Pathfinder miserable fuel economy

Just purchased a 95 Pathy 5sp RWD in great shape, but I'm getting about 14mpg hwy and 11 city!!! We've checked everything you'd think of off the bat that could cause such poor mileage. Self diagnostic revealed no error codes.
Any thoughts?

Please?

Kevin

Pathy's seem to get horrible gas mileage in the real cold weather and since you're in Detroit...

Just make sure all the normal maintance has been done like plugs, fuel filter,air filter,etc...

You can also try replacing the 02 sensor and see if that helps even though it didn't throw a code.

How many miles on the rig?

Question

110K, and yes, it's colder'n seal lips in Detroit right now.

If the O2 sensor were bad, wouldn't it throw a code?

Could a bad EGR valve be responsible for a 8mpg dip in performance?

Yeah, cold weather could cause really poor gas mileage, expecially if you are driving in snow. On you rig, if it was mine, I'd go through and replace everything, timing belt (and water pump), plugs, cap rotor, wires, all fluids (engine oil, coolant, brake, clutch, transmission front and rear diffs, t-case, fuel and air filters, repack bearings etc, etc, etc. It is funny how many people sell thier vehicles before the second 60,000 mile service is due. Since you just bought one with 110k, my guess is the previous owner had a shop estimate the cost and it scared the crap out of them. You can do all this fairly easily. Also, a fairly easy check is timing. If someone is wanting more power, they could have cranked the distributor throwing timing off and sacrificing mileage for power (not a real fair tradeoff). It may cost you about 200-300 in parts for all this, but it really is a small percentage of what a repair/maintenance facility would charge.
