SOURCE: 2001 Ford Windstar runs rough.

remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out

SOURCE: running rough, spark plugs, distributor cap, rotor

First thing you need to know is which cylinders are missing. Then, don't forget there is an engine beneath the electronics. Do a quick test with a vacuum gauge and do a compression test. Check the distributor shaft for side play. If everything checks out good, then do electronic component testing. have a code check run (many parts stores do this free) and get a chiltons or haynes manual and follow test procedures in there.
I refrain from giving repair suggestions with problems like yours because people keep changing instead of testing parts. When I work on my vehicles or other peoples cars, I do testing to avoid buying expensive parts that most times won't correct the problem. At this point the most I'd suggest is to clean the mass air flow sensor wires with a Q-tip and carb cleaner...that often helps and is free. If you run into a problem with whatever you find, ask and I'll try to help.
good luck

SOURCE: engine runs rough at idle and bucks at highway

I had a similar problem in a 1994 Taurus, and after spending nearly 300$ on ignition parts, it turns out the problem was a bad spark plug wire that cost me 8.88$ to replace.

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.

Ford ranger #4cylinder misfire, 4.0/ v-6 already changed plugs, wires& coil pack.


the misfire may be caused by a fuel injector that is not working. Do you have a good spark at that cylinder?. If so try the redneck approach to fixing a stuck fuel injector. first make sure the fuel injector plug is clean(terminals) and on tight. With the engine running, Take a long socket extension and place an end on the fuel inector plastic housing, tap on the other end with a hammer. LIGHT taps!!! remember its just plastic! sometimes this is enough to free up a stuck injector. If not, then replace the injector.

before you do this Unplug the injector and see if the engine idle changes. Also check for an electrcal pulse at the injector plug with engine running.

My tuck idles low and spits gas out the exhaust


Since you have replaced all those parts already, I would suggest checking out the egr valve. Also I was wondering how the coilpacks or distributor are acting? Is the truck firing on all cylinders? Very possible you have leaky injector also.
