Check and clean (or replace if need be) the mass airflow sensor and the oxygen sensor that is mounted before the catalytic converter - these are the two main contributors to fuel mileage, good or bad. It's also a good idea to do a basic tuneup as well - change your oil and filter, air filter, spark plugs, spark wires, cap, and rotor. Get a bottle of Seafoam (from a parts store, right on the shelf with the other engine chemicals and additives) and dump it in the fuel tank, then top off the gas. You're probably looking at about $100 or so for all the tuneup parts (plus the cost of the oxygen sensor or mass air sensor if they need replacement), but it's money well-spent. I did exactly this treatment on my girlfriend's 93 Civic (178k miles, 1.5L four cylinder, auto transmission) and her mileage went from 26mpg to 44mpg with $110 and a couple hours invested.

I have a 1993 Geo Metro and recently it has a MAJOR loss of power going up hill!


assuming its the engine? is it, and not transmission slipping? A/T?
1:the 60k tuneup in the operators guide done?
the 3 causes are. (takes tools to find which, in most cases.
lost compression , hot engine?
poor spark (weak or not timed right)
poor fueling.
there are simple tests for each.
we can do the tests, or guess?

Geo metro dies


Your catalytic convertor is stopped up, common problem on Geo's! Will burn an exhaust valve if you keep driving it!

Geo Metro 1994, diagnose no fuel presure problem.


Quite a few things can cause a car to die after idling for awhile, but if you have verified that the fuel pressure is actually dropping when the motor dies, the likely culprits are:
1) Electric fuel pump in the gas tank is bad
2) The fuel pressure regulator (on the throttle body) is bad
3) An electrical problem in the power to the fuel pump (like a bad fuel pump relay or lose ground wire to the relay's circuit)
