Just bit the bullet and went for your plug…. Bought an Alldat.com subscription.
At first Nothing….None of the tsb's (as listed) by the site below are shown at Alldata
for ping problems e.g.,
The list goes on- Bulletin Number’s: 15095, 6321, 14076, 14366, 0073, 00248
But then I found a real TSB Number 00-7-3. And it stated just what you said:
Replace Coil, if between a set of code numbers… and then it also said replace the PCM
Ackkkk. That says to me a faulty PCM. … i.e maybe it doesn’t HEAR the knock sensor.
Anyway, after weighing my options, (i.e., how long of paying for Premium gas would it take to pay back for a new PCM, coil and time spent fixing something on an 8 year old vehicle.) I’ll just go for the gas. I repeat Ackkkkk….
All in all, Thanks for your help. I got the right answers…

Well, I didn't 'recommend' pulling the SPNG (or whatever it is) connector. Maybe it could be read as I did 'suggest' it. But I really don't suggest it. Especially since a 3L needs all the power it can generate, and retarding the spark will reduce power.
But, I've read that this is exactly what some Ford service people have done when people complain of the 3L pinging - pulling the connector.
The motor has a design problem, has had it for years and years, and Ford does nothing about it. I've not heard of anyone actually having any damage from the pinging.

Yes I did check vacuum leaks, even cleaned the MAF filament as suggested at TheRangerStation.com. Very frustrating. I think this engine should be rated for a higher-octane fuel. I’m still going to try the timing light/ whack the engine with a wrench test- to see if the timing retards. From what I’ve read, the resonant frequency of the Piezzo element is about 15 KHz, about the same as hitting an engine with a wrench… Besides at this point, it might be fun.
Thanks for your help. As I said above.. I got the right answers.

Well that didn’t work. (Wrapping the wrench on the block)
Saw it at
I tried it on the 3.0L Ranger, and I could’ see any perceptible change. I didn’t know if the sensor was bad or if the test was bogus, so then I tried it on my 4.2L F150. Same thing. There may have been a small change but it was too small to be conclusive.
To make matter worse my wife came out and asked what I was doing. I told her and then showed her the posts I put here. The only thing she picked up on was a major Blooper in one of my posts. She’s still laughing.

i am probably just going to get rid of my 85 ranger stick 4x4 4cyl. I bought the truck for a case of beer and ten bucks. the guy who had it before him raged on it real bad. now the timing sprockets only turn when i mess with the bottom sprocket and then turn the second one. the top sprocket dosent move. and the belt just sits there. i think i should just get a new engine. but i just wanted to see if there was anything i could do to fix it. i dont have the money for new so i want to fix . please help me out.

2002 ford ranger no check engine light but no power. will not pass 3000 rpm. Hits about 3200 rpm and starts to miss fire and bog down wont pass that point. Dont matter if in drive or neutral still does it any one have any ideas. No trouble lights have come on.

My truck will not run when it gets hot. The water temp is fine but when I first start it up it runs but after about ten minutes it sounds like it's casping for air and woun't go over 5 miles and then bobs out. Please help me. I've tune it up change gas filteres.

dude, you need a cat converter, or a MAF meter. Both of those will cause the exact result you are seeing. Take a thermometer(non-contact) and check before and after the cat temps while the truck is running and warmed up. THere should be no more than a 50 degree difference from the inlet pipe to the outlet pipe. If there is, then the cat is done. If they are fine, then the truck is limiting itself electronically somehow. THis would send me the direction of the Mass Air Flow meter (MAF) and in a hurry. If neither of those 2 make a difference, save yourself some money and time and take it to a dealer. They can find it quickly if those don't work. Good Luck.
