Have you verified that fuel pressure is correct?
You might want to remove the injector rail and inspect it inside for a rust or garbage that can be clogging injectors.

1998 ranger 2.5 manual enging miss


ck for leak at intake. if no leak pcm/ecm may be sending fire command to slow to # 1 . the fuel injector is always hot the ecm sends a ground to the injector. even new parts can be bad ck inj, with ohm meter resistance should be the same between each inj. im not sure of the specifications but they should read the same my jimmy specs are 1.9-2.1 any other reading is bad . no resistance or lower or higher readings my injector would be bad. 140 is good reading, timing can be off a little and still run but rough like a miss. a code wont set most misfires will set a dtc or flash the engine light to let you know damage to cat system is happening , to much fuel a system rich,to little a lean. a bad mass airflow meter can also cause a misfiring or rough idle ck with scanner if dirty clean with brake cleaner first before replacing . hope this helps some let me know how it goes.

I changed wires ,spark plugs, two coil packs and the two cylinders are still not firing


Do you have a simple miss on 2 cylinders? If so, you might be looking at a fuel injection problem, specificially a computer problem not firing the fuel injectors for the two cylinders in question.

I would investigate that route.

Could also be a module for the coil packs, that the coil packs sit on.

4th cylander keeps misfiring new plugs and wires


first question is it a four cyl? or six did u change the coil pack plug wire if a four cyl? did u use ngk plugs to replace the plugs? or it may be a fuel inj you would have to swap fuel injs with a different cyl to see if it follows the inj or stays with the cyl, if it stays may need to diag that cyl further compression check etc

is the car missing when driving? 2000 and on has coil over plug's there are no wires. Is the check engine light on? if so go to an Auto Zone parts store or one that will scan the car computer for free and get the codes out to pin point the problem. Sounds like the cars miss firing. it could be more than one coil and or plug going bad. Did you replace any coil packs? Bad coil packs are 90% of all miss fires on todays cars and trucks.

double check plug wires to be sure they go to the right cylinders. After that i would check fuel injectors
You need a listening device and listen for metallic clicking sound. Bad injectors will be silent and they do cause the same miss

Missing on two cylinders


Sometimes your plug wire go out. Try swapping 1 plug wire to another. In other words, the one the firing, put that plug wire on the one that is fireing. You might have to buy a set of wires.
