1987 Ford F150 302 auto 110,000
new tune up plugs wires cap.
Doesn't use oil

It seems that when I first got this truck I got about 15-16 mpg

I don't seem to be getting 10 now.

It seems to drive fine except for a slight pinging when I accelerate after the engine warms up.

Maybe someone tell me which sensors or componets I should check.

Thanks for the help

What is the best way to clean the injectors. I don't think they have ever been cleaned.

You can go to any oil change place and get a fuel system cleaned. It costs about $75.00 but its worth it.
