ive been have a persistent and worsening problem with my 93 ranger ext cab 4x4 manual with a 4.0 OHV motor that's my daily driver. runs fine then all of a sudden and for no reason it will lose power start to miss (like its running on 3cylinders) and the engine will completely cut out over half throttle. it is a completely random occurrence but is happening more and more frequently. the CEL comes on but ONLY when it is messing up and it immediately goes out when it clears up, the problem comes and goes like flipping a light switch. I tried putting a scanner on it to see what codes come up but since it doesn't act up when I have the scanner around and it doesn't save codes I cannot pull anything up. also what is weird is sometimes I can lightly press the clutch pedal when it acts up and itll run fine. yesterday when I got home it was acting up bad, I let it idle in the driveway trying to see if I could figure something out and it was cutting in and out about 5 sec of running bad then 5sec of running good and it just went back and forth doing that, the exhaust smelled like and old carbed motor (like it was dumping fuel). anybody have any ideas? im leaning towards O2 sensors but im tired of throwing parts at it and so is my bank account.
ive done the usual 4.0 problem fixes in hopes of fixing the problem with no success. cleaned MAF, new TPS, new coil pack, new idle air control, new coolant temp sensor, plugs/wires are about a year old, fuel pressure good, fuel pump replaced about 2yr ago, throttle body cleaned
