It's missing, but I've changed the plugs, and wires, and the fuel filter?

missing is more likely from injectors and low fuel pressure than from plugs and wires
have the injectors checked for good tips and correct operation

I swap my engine on my 03 ranger 3.0 flex fuel,with one from a 02 ranger gas fuel. It was running rough until I put my old fuel rail and injectors.But I still have a miss on cylinder #3 already install new...

Check compression in number three. You could have bought a bad engine. And yes. You need to change every sensor. If they don't match with the plugs. replace the engine. There is a reason for different engine codes. You should have stuck with them.

Why does my 89 pontiac 6000le idle slightly rough after having the fuel injectors replaced? The reason I had to have them replaced was because of the ethanol in todays fuel ruined the original fuel in

If it is idling like it was before the inj were replaced then you have fixed the wrong problem the ethonol doesn't damage injectors you probably have a spark plug wire that is bad or a coilpack is bad or you have a fouled spark plug? A compression test can tell you of any problems with the valves! The injectors are designed to be compatible with flamible liquids ie gasoline or alcohol! I have been a mechanic for 23 years and have never seen inj fail due to alcohol in today's gasolines! You might have been scammed? Anytime you have repairs done request your old parts to be returned to you! You might have to take the mechanic who claimed he replaced your inj to small claims court! Try replacing the plug wires and the spark plugs first if no change then get carburetor cleaner and with the engine running spray the inside of the throttle body where it is black with the throttle open and engine rpms increased if that doesn't change it the coil packs might be going bad there are three so buy all three as a set so you don't have to change them at different intervals! Depending on mileage the timing belt is reccommended to be changed at 150,000 miles the spark plugs are due at 100,000 the coil packs should last over 200,000 miles so I'm guessing it is time for major preventative maintenance? The timing belt being worn can cause rough idle too!

I need to change the head gasket on my 4 cyclinder tacoma it is getting radom miss fires

we usually replace head gaskets when there is an overeating problem or leak problem, if you saw coolant in the spark plugs or if the misfire come with a thick white smoke from the tail pipe, then this is reason enough to do the head gasket job.

for random misfire we got spark plug wires high resistance,
weak coil,
bad fuel,
weak fuel pump.
bad injectors.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.

2003 dodge stratus multiple misfire

you hooked the wires up wrong the whole fuel injector wire assembly goes up to the fire wall then clips into main wires
the fuel injector track is one track with wires
when you replace wires you also want to replace the injectors to match
buy new engine wire harness this will solve the problem
