3L's are well known to 'ping'. Even when new. But mid-grade or top-grade gas usually reduces or eliminates this. You might have something else wrong. On 4L's, if the lower intake bolts are loose, they will ping. I've never heard of this problem happening on 3L's, but you might see if these bolts are loose.
 
Ford sometimes replaces the coil pack with one that is supposedly more powerful (or something). On many motors this doesn't help much. There is also a SPRUG connector, or something like this, that can be unplugged to help. This basically retards the timing, which also reduces power. (I don't know where this connector is at, can't help with doing this yourself.)

You IAC (Idle Air Control) valve is causing this. It is a chrome and black canister, the diameter of a 35mm file canistor but longer, on the left side on the intake manifold. With a 2 wire connector going into it. This controls the idle RPM of the motor. If it is bad it can cause this hum/vibration. It will also cause the idle to 'surge' up and down.
 
There are 2 bolts that hold this on. Be careful with the gasket behind it, do not mess it up. Remove the electric connector. This basically is an electrical solonoid valve that bleeds air into the intake manifold. The valve part gets clogged with carbon and gas gunk. It can be carefully cleaned with carb cleaner. DO NOT GET CLEANER INTO THE ELECTRICAL END OF THIS, it will eat up the coil and ruin it.
 
If you don't want to try to clean it, aftermarket parts houses sell these. About $65 or so?

High octane fuel helps out some but you can still hear it.
 I've thought about the timing problem and talked to a ford dealer and they wont me to give them $70 to hook it up on their computer just to see if they have an update for the problem. Didn't think about the knock sensor though,, i'll have to check into that. Thanks for the ideas.

I've got the same problem, no solution. The 'richer fuel' suggestion never worked for mine. My truck had 68k on it, now has 148k, and it's only there when I'm pulling heavy loads, up hills or accelerating. IE - whenever the engine is pushed harder.

Well light "pinging" for abbreviated amounts of time isn't really harmful...what I caution folks about is heavy prolonged pinging that goes on most of the time or that is heavy WHILE the engine is working very hard. This can be dangerous, as the "ping" is actually the internal parts of your engine rattling around in there, under stress.

The ping is actually pre-ignition. It happens when the cylinder and combustion portion of the head is very hot. When the timing and mixture is set correctly, the ping should go away. Ford sets the timing and mixture right at the point of a slight ping. This is the cleanest the engine will run. I had a pinging problem with my 1999 Ranger (3.0), you could just touch the throttle and hear a ping which turned into a full blown rattle. The Ford dealer said it was normal. Well it got worse and I took it back. They used a later program for the computer and it stopped. I still have the truck and it does not ping on regular gas under heavy load.

MY OD LIGHT WAS FLASHING IS THAT AN INDICATION THAT THERE IS ANOTHER PROBLEM?

#1834 of 2986 99 Ranger O2 sensor by rangermang

Dec 03, 2005 (2:26 pm)

My 99 2.5L 4 cyl ranger has been getting about 17 mpg average, so I had a friend diagnose the problem, and it was my O2 sensor. I was wondering how you can find out whch O2 sensor is the faulty one, and if I can fix it myself. I'm open to any sugestions, thanks.

I'm in the middle of replacing the drag link on a '94 4x4 4.0 and I stripped the nut on the adjusting sleeve. I am at wits end trying to figure out how to remove this bleeping nut. Any suggestions?
