Need to know the spark plug gap on a 1995 ford ranger 4 cylinder?

It depends on the spark plugs that have been used. Some are pre gapped, some have three preset side electrodes around the edge. Gapping spark plugs is not as critical as the old days due to modern CDI ignition systems which give a much larger spark and huge improvements in spark plug technology.

0.044", IT16 Denso Iridium Spark Plugs are the best for your truck... they last 60K miles on average, save gas and add power.
Use thread antisieze lube on the first 2 to 3 three threads of the spark plug, it makes it easier to remove them in 5 or 6 years time. Check your plug wires one at a time too for signs of wear and cracking at the boots. A peak inside the distributor cap is also a good practice... any black carbon deposits at the electrodes is a sign it needs replacing along with the rotor. Your truck has a 2.3 liter, 4 cylinder engine.

1.10 mm

plug gap should be .045". if you look under the hood somewhere you might still have the decal that has this information on it.

If I had a nickel for every time a kid screwed my over at the parts store-you only need 4- some old datsuns had 2 per cylinder nothing currently does though- cheers Denny

0.042-0.046 is the correct gap for your spark plugs,If it is backfiring now and was not before make sure you were not sold platinum bosch plugs and if you are using factory plugs,then I be looking for a faulty spark plug.Also make sure the firing order is correct.

First thing you'll need to do is do a compression check. If that cylinder is OK mechanically, then you'll either have a problem with an injector or spark. Pull that plug wire off and put a spare spark plug into that wire while it is laying on a metal part of the engine. Start the engine, if that plug is sparking while the engine is running and you know you have a good plug in that cylinder, then you may have a problem with the injector or the wiring to it. If you can get the connector to that injector off, and wire a small 6 volt flashlight bulb to it's socket, and it flashes while the engine is running, then you know you have power to the injector. If all the previous tests have proved alright up to this point, then you likely have a bad injector.

it realy wont bother the car to much what you set it at but go for a gap of 18 to 25 th of an inch
