#2942 of 2986 My 2000 Ranger keeps misfiring!!! HELP
Nov 08, 2011 (4:17 pm)
I have a 2000 Ford Ranger 6 cyl 4.0 liter.. It keeps misfiring, and bank 1 and bank 2 lean. I changed all 6 plugs, wires, and the coil pack. Afterwards it seemed better, but wasn't fixed. Check Engline light is back on. Before, OBD said cylinder 4 and 6 were misfiring and now it's cylinder 1. The o2 sensor underneath on my tailpipe was recently changed. I hooked up a gauge showing fuel pressure and it read 72psi.. It's supposed to be between 54-62.. Would this cause it to run bad and misfire?? I need help, next step is to take it to the dearlership and I want to avoid that If I can..

Ok, my experience is with a 94 4Liter. And I think you have a completely different motor, it changed about 1999 or so.
But on mine, the intake loosened up. It started using a lot of oil all at once. It went from using less than a quart in a 4,000 mile chance cycle, to one morning turning on the 'Low Oil' light, and it was about 1 1/2 quart low. I read about the loose bolts, so I went over the intake tightening it down. Started in the center, then back and forth, toward both end. And several were loose, and all needed some tightening.
This solved my oil usage problem instantly.
It had 8 or 9mm bolt heads, and I used a 1/4 inch drive with a flex drive.
Just something you might check. On mine the loose intake allowed an oil passage have oil pulled into the intake. On yours, it might be allowing an air leak into the intake, making it run lean. Also look at all the rubber hoses. A leak in any one might make it run lean. Look also at the large rubber, or plastic hose the pulls air from the air filter into the intake. A leak here sure would make it run lean.
#2944 of 2986 Bad Clutch Fan ?
Nov 27, 2011 (6:22 pm)
I have a 99 ranger 98,000 milkes with the 3.0 Flex motor. With the engine off the fan turns with same amount of movement/ resistance at operating temp as it does when it's cold . Should I not be able to move it at all once the the engine has become hot ? I am guessing the clutch is bad ? Any help is appreciated..thanks in advance

I'm not sure, but I would think you have electric fan/s on this car. The viscous coupling fan you described haven't been used on any of my autos in many years.
An electric fan will freewheel the same at cold or hot temps.

the fan clutch is set to move weather it is running or not. it is filled with oil so it turns at a specified factory speed, if it is to tight it will cause the engine to overheat same way if it turns to freely. if it needs to be replaced most parts stores can tell if it's bad.
hope this helps

The orginial poster was talking about a 1999 Ranger.
Doesn't it have an electric fan?

did you look under the hood to see if it is electric? if it's on the engine then it has a clutch, if it's on the radiator then it's electric, you mentioned clutch fan in your origonal post

I'm having a hard time finding antifreeze that matches the specs as listed in my owner's manual. I've got a 2008 Ranger 3.0L V6 and the spec is WSS-M97B51-A1. Would one of the PEAK or PRESTONE brands that say "good for all makes and models" work?

if it says good for all makes and models, yes!
