Question about 1994 Ford Ranger Supercab
Need help pinpointing reason why my 1994 ford ranger idles roughly, sluggish acceleration, power cuts in and out when pushing the accelerator, loses power and speed after a few minutes of driving at approx 55 mph, does not resume power until vehicle decreases speed to about 35 mph or when coming to a stop, also shifts rough and rpm's exceed higher than normal before shifting to next gear. we replaced the fuel filter, checked vacuum lines, air filters, plugs and wires, could it be a oxygen sensor? if so which one?
This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.
