Well given that your truck is fuel injected it should have a mass airflow sensor in the air intake duct attached to the broken air cleaner housing. Unplug this sensor and see if it changes the running condition. If it does your broken box may be affecting the airflow across the mass air sensor. Also check for broken vacuum lines and the intake manifold is notorious for vacuum leaks. Will running bad spray intake with a flammable brake cleaner. Be carful. If you get the engine to change with the brake cleaner you just found your vacuum leak

Sounds like it is loading up on gas, try using a cleaner in your fuel, or a aerosol can of cleaner that you can spray directly into the carb. while it is running. It this seems to help you may need to have it rebuilt.

My 2005 Ranger won't run. The check engine light reads cyl 2 misfire so we changed the plugs. We also changed the fuel filter. It starts but won't run. It sputters and chugs. Don't know what else to do?...


You more than likely have a bad spark plug wire on cylinder # 2. But considering that when it starts it only sputters and chugs, you have more wrong than just one bad plug wire. Are you 100% positive you have the plug wires connected correctly. Here is a diagram of both the 3.0 & 4.0 V6. You may also have a bad coil pack. clay58_44.png

well i'd call the basterd and ask him what he wants to do about it , or take him to court as he did not disclose these problems. Or did he? I would check the fuel system for leaks which causes engine to get air and less fuel than it requires or check tank for leak and also check motor for bad vacuum lines and intake gaskets. spark plugs check.

I have a 1992 ford ranger it has a 2.3L four cylinder engine.it has a ticking noise so i think its a lifter.its real bad when i first start it and slows alittle bit when the engine worms up,the ticking...


Before you change lifters try this trick. Drain 2 quarts of oil from the engine and top it off with auto trans fluid. Let the truck idle for 45 minutes or until quite , then change the oil and filter. I have made many lifters get quiet this way and it will not damage engine.

My 1990 ford ranger running rough obvious vacuum leak idles 7oo rpm and while in gear with the break on truck nearly dies but idles ok but not great in park


Use a length of rubber hose to listen around for the leak.
Or use some brakeclean or starting fluid to see where the leak is by it reving up. (stay away from the alternator).
Pinch off any vacuum hoses, one at a time, looking for one that makes a difference.
