Here's my story:
1.) Got a "Service Enging Soon" light - took my C1500 with 5.7 to Autozone to check codes. They give 3 different things that could cause whatever code - said most likely catalytic converters. Fixed that and code went away.
2.) A week later the light comes back on - this time Autozone says "Multiple Engine Misfire" - probable cause plugs and wires. Changed them and light went away.
3.) This weekend we were towing our RV and start getting a very loud miss trying to stay at 70 MPH going up the Missouri Ozarks. After the light comes on again, we pull into a local Autozone to check the code - another "Multiple Engine Misfire". The guy wanted to sell some more plugs and wires. The only thing I could think about at the time was the distributor cap and rotor. The old ones were corroded. This didn't fix the problem at all (add this note: when I tightened down the rear screw on the distributor I did hear a "click" - I wonder if I cracked this cap!). Now I'm wondering if the fuel filter is stopping up.
With 127,000 miles, most of this stuff needs replacing anyway. I just hope something fixes this. I have to be towing to get this to happen. I can run around very quickly with AC running and nothing happens.

All of them or just certain ones? Did an engine analyser tell you this?
Well I have a code checker and every time it would say mutiple cylinder misfire I took for granted since it could not pin point which one I change them all.

Did you use rebuilt injectors or new ones? New ones are pricey, especially buying 8! But I don't see 8! How many do these engines have? Fords have had multiport for many years.
I used new ones and yes there are eight.

Where are they and how hard are they to get too?
