2000 Ford Ranger

It idles really rough sometimes and we just changed the spark plugs and wires. And it kinda sounds like its gonna die. It also does it at higher rpms.

The plenium might be cracked, which is pretty common on rangers, or the idle silinoid spring valve is broken

1994 Ford Ranger low power

Ok, it sounds as though your fuel pressure regulator or injector lines or injectors are leaking. What engine is in the vehicle? Is the engine light flashing? Does it start hard and blow smoke on startup?

You have two coils on this engine. Test each wire for spark with the engine running. You'll find at least one wire not sparking. replace the coil that has the wire that's not sparking.

Why does my 2000 ranger have a rough idle?

Thanks for choosing FixYa and welcome to the site. There are a few different things that can cause this rough idle to occur. Check your vacuum hoses for leaks. You could have a clogged air filter or fuel filter. If you haven't had a tune up in a long time, try to get it done. Change your spark plugs/coils, wires, distributor cap, coil pack. Check for any loose hoses or wires on the engine also. You might want to check your pcv valve as well. Anyone of these can cause this to happen so check then all out.

Hey Troy code 301 is cylinder # 1 miss fire, I know you know that, but have you check your fuel injector, that what is sound like to me, of corse me not beening there would be my best guess, look's like you have checked every thing else, good luck.

I have a 2003 Ford Ranger 3 liter. I just changed

Did you replace the wires? if not you may have broken a couple of wires. Not sure what fire wire is unless you mean the spark plug wires. Also did it do this before you replaced the plugs? need to know.

01 ford ranger 4x4 4.0V6-- rough idle like it wants to cut off. loses power or studders under acceleration. struggles to get up to 55 or 60

I agree. Try replacing the spark plugs, install new spark plug wires, change the air filter, change the fuel filter, and test the battery and alternator. Run a bottle of fuel system cleaner and water remover through it. To replace the spark plugs you'll most likely have to go through the wheel wells cause of their hard accessibility from the top. The fuel filter is located on the inside of the frame on the driver's side. Hope this helps. God bless

Need PCM WIRING DIAGRAM for 1999 ford ranger 3.0L v6 4x4 flex fuel engine vin letter V bought a 1999 ford ranger 4x4, 3.0 liter v-6 Flex Fuel vin letter V, back in February .... I drove it less than 200 miles and the engine blew ....... Here it is now, December, and I just had the engine replaced with a great used engine, .... but the check engine light does not light up, for the emissions test, ... the engine is running exceptionally well. .... I changed the check engine bulb, and I have power at the bulb ... and if I touch the bulb with the test light and ground it ... the check enging light-bulb, lights-up. ... So I want to check to see if the check engine light wire, is OPEN somewhere, because I Think that the creepy people that I bought the vehicle, somehow may have rigged the thing, so that the light would not light-up, and I can't find the pin-diagram, for this vehicle... and cant find it in the oin-line manual .... I am suspicious that the wrong wiring harness, is possibly installed, .... all I have been able to find on google images, are 4.o ranger PCM wiring diagrams, and can not find any for this 99 3.0 flex fuel vin number V..... everything that I have looked at shows a diferent color wire than I have on this one,... running to the check-engine-light, .... the 4.0 shows a pink with light green wire, for the check engine light... My 3.0 going from top left to right, has a seemingly, light-green / white wire, ... then next to the right, is a red / dark blue wire, the next is a white wire, to the right of that one ... The engine was swapped just before I bought this truck, and I am just trying to figure out, what these idiots did, with this engine and/or wiring-harness
