I have 4cy 8plugs ford ranger that is not running right?

I have a ford ranger 1992 that is not running right it drinking a lot of gas and its losing power what can I do to fix it

4cy 8 plugs? It could be many things, vacuum leak, EGR valve, bad fuel injector, temp sensor, MAF or MAP sensor, dirty air filter, low tire pressure, etc.

Few things i would check
check your injection system. Also check your gas cap. Gas vapors can leak out.
you may need a tune up (for the loss of power)
check for misfires (if you have an engine light)
correct tire pressure can also save u gas
