there are a lot of things that could cause this if running rich would take a look at the air intake temp sensor the air intake or "air charge" sensor will send signals to run rich if is not seeing the right relative pressure and temperature~ https://www.google.com/#q=1993+ford+ranger+air+intake+temperature+s ensor&tbm=shop&spd=9646602305992411656

a fuel pressure regulator can get a torn diaphragm or leakin' vacuum hose...these will NOT show up on your diagnostic report~ https://www.google.com/#q=1993+ford+ranger+fuel+pressure+regulator&tbm =shop

the ole TPS or throttle position sensor is what tells the computer where your foot is...could send errant signals....test...when bad, replace~ https://www.google.com/#q=1993+ford+ranger+accelerator+position+sensor &tbm=shop

or you can chase your tail with process of elimination but can get expensive ... checking the timing is free...lol gl

okay definately has a chain~

lousy cartoon, but it's all I could find for tne 2.3 liter ford~

where do you see a chain????

clearly it is a belt.... I have changed many... not on the WEB like you but physically did it myself with my own hands not touch a key board or mouse... all real tools not fantasy tools or thing I should I think I can do because I can copy and paste! lol hope this clears things up...

2.3 I4 in the '93 model should be the same as the one in a '94 model... it has a timing belt. Mine broke a few months ago and fairly easy to replace, should be easier to adjust a tooth or two.

Best Answer

This has a 2 sided/double ignition module if it has 2 spark plugs per cylinder.It will still run with no power on one module though.Have the spark plugs checked to make sure all 8 are firing.

Operator_13 shared a diagram that looks like it... will need to pull crank pulley and fan belt first, then remove the plastic cover. The small pulley on center left will be the equivalent of the tentioner pulley on the fan belt. The double ignition module... one being out hasn't affected mine that much.
