The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

1991 Ford Ranger Problems
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing deferential clutch kit. An updated differential clutch kit available.
If you experience cold starting problems, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steadily and run when the accelerator pedal is not pressed.
it seems to bog down when u press on the accelerator if u go slow i mean real slow it does ok also seems to bog down when it reaches 3k rpm like its starving for fuel or getting too much
The front brakes may stick, bind, or grab. This can happen when the front brake caliper pins become corroded. Cleaning or replacing the caliper pins will be necessary to correct this problem.

The body has stood the test of time as one of my favorites. I'm not a fan of the round body style currently used. The interior gets less than 5 stars because the drivers side seat is lop sided sloping towards the door. The passenger side front brake hose collapsed on me the first day I had the truck, causing the caliper to seize up. Fixed for less than $20, but still unexpected. The drive train for a 19 year old truck is very strong for a 2.3L and I would recommend this vehicle as a first driver for any parents with teen drivers. Be mindful of these areas I'm commenting on though. Electrical and lights hold up well but the temperature gauge never leaves cold. It does move but not much. The tach has also shown spikes from time to time, when the engine was at idle at a traffic light. The engine runs solid but the starter is very noisy upon engagement. I may just have a localized problem due to a recent clutch replacement. Always check all bolts and the direction of your flywheel. Exhaust and emissions are on the mark, I have driven behind this truck and smelled no fumes, seen no smoke. The heat doesn't get really hot, its just tolerable so that you don't freeze. The AC doesn't work at all due to Compressor lock up. Only $230 to replace components and get AC back online. Suspension at 137k has to be looked at. I replaced all 4 shocks and now have a solid ride on the interstate. Something to keep in mind. I hope this review helps others in their search for a second vehicle or their very first.
