Misfiring engine?

Engine Performance problem
1997 Ford Ranger 6 cyl Four Wheel Drive Automatic alot miles

I have had a problem with this vehicle for a while and i'm hoping I can finally resolve the problem. It started as a misfire so I figure since I had over 200000 miles it was time now just a note I bought with this many miles anyway to tune her up so I did and nothing changed the scanner kept telling me #2and #4 misfire so I said to myself its probably the coil pack, nope its not that then a friend suggests fuel injectors I had to have two of them replaced and still skips the engine has only about 55000 miles on it and it was a rebuilt so I thought compression nope not that either it has 150lbs across the board then I was told it could be a fuel pressure regulator guess what nope ! So I did a fuel pressure check and it has at start up around twenty pounds and at idle it has about 35 ish can this be my problem? O by the way I also replaced the intake gasket because two people had suggested at one time this is what they encountered. So I say HELP !

My Ranger every time that I crank it goes through a really rough spell, After I crank it seems to run ok for a minute. After that it runs so bad that you would think it jumped time. I can turn the key off and on without letting it die and it clears up for a minute and then starts back missing. If I keep it running by patting the gas in about 30 seconds it clears up and runs great until the next time I recrank and it starts all over again. I have no clue. Please help.
Thanks,

Start with spark plugs.
Replace them and inspect the old ones to see if they have any cracks or missing parts on them. Continue with replacing them. If same problem re-occurs, it could be that either the piston or piston wall may be cracked, and may need a new engine.

After completing a valve job I have noticed a pause or blip while idiling. This can also be seen if one puts a timing llight on any sparkplug wire and watch the light. This seems like a spasmatic missfire. Has anyone a idea of cause?

No check engine light, cam sensor wasn't disturbed during previous repair, crank sensor seems good gap has been varried with no change.
Seems to me that if one of the sensors was bad the miss would happen within each revolution of the engine. Also if it were the coil that cylinder would have a continous miss. This miss happens once every few seconds which would be several revolutions of the engine. It also doesn't seem to be at any time other than idle.

Bought this truck used about 2 years ago. Changed plugs and plug wires do to an engine miss and all was good. Year later miss came back, engine code " mis fire no 4 cylinder". Changed plug, miss corrected. Year later same thing. Had to replace only No 4 plug to correct engine miss.
Any idea what could be causing this. Plug looks good when I pull it. Doesn't look fouled.

I have a 2.3 5 speed ranger. My engine light came on, it said cylinder 1 misfire. I checked my spark plugs, got a spark, checked my wires, got a spark. Checked the coils, number 4 worked fine, but number 1 did not. However, on an ohm check, both coils got a good readout. If a coil gets a good readout, but is not firing, what could the problem be?

Would the crank position sensor effect just one coil, even though 1 and 4 are supposed to fire together?

My Truck is a 1996 2.3 I4 Ford Ranger. The problem I am currently having is that the truck misses and feels like it is bogging out after about 3rpms. It started by doing it occasionally but recently started doing it whenever I drive. It is almost impossible to go over 50mph sometimes. I replaced the fuel pump about 8 months ago and it ran perfect since. As soon as it started acting up I changed the plugs, coils, wires, fuel filter, air filter, cleaned the MAF and throttle body. I cannot figure out what it is for the life of me. Could it be an erg valve stuck? Stopped up cat?

I have 96 ford ranger v6 4.0. For about a year I have had a head gasket out. I have tried several liquid fixes with no success. About a month ago my truck became gutless and started to misfire. Shortly after my cousin and I just finished up the head job. The truck was sitting for a while I have tried driving it, and it shakes and misfires just like before and is shooting fuel out of the tail pipe. I have checked all the hoses, the spark wires are only about a year old, and everything appears to be fine. Could the bad head gasket and the fact that I put those additives in my radiator have caused my Thermal Valve Vaccum/EGRvalve, PVC, or O2 sensors to go out(I replaced my O2 sensors 6 months ago)?
