Still hunting for the solution...
ping...ping...ping....definately NOT music to my ears! I am still trying to find the solution to my ping and power loss problem. Does anyone know of anything else i can try. The dealer doesnt know what the problem is. I have already cleaned the MAF, changed the plugs, changed the DPFE sensor, cleaned and checked the EGR valve, replaced PCV valve, ran multiple types of injector cleaner through my gas, cleaned the IAC valve, had an induction cleaning done to remove carbon deposits. Im starting to think it might be a bad O2 sensor, but wouldnt that throw a CEL? any advise would be appreciated. Also, after the dealer did the induction cleaning to remove carbon, my truck takes longer to come to idle...it runs about 200-300 rpm above idle for about 4 or 5 seconds, then it finally slows to idle speed. why could this be? thanks!

Have you replaced the fuel filter yet, most tech's reccoment 30k intervals.
One bad tank of gas can plug the filter up in a hurry. Regardless of miles on the filter.

Hey there bassaway. I'd figure, I've got a couple of cents (no sence), so here goes. The dealer may have adjusted the choke, or timing when you had it in there. The rise in rpm is probably do to that. You can re-check the timing if you want to. The pinging may be assosciated with that also. The next time you get some fuel, pay a couple of bucks more and up the octane to the next level. With a 2000 truck, there shouldn't be any timing adjustmants made, unless the dealer found something. Which they should have told you about. Try another gas station for gas if you need to. Changing the exhaust from the cat(s) back, shouldn't affect anything on your rig. Get back to us.... Thanks

hey scooter, yeah...the dealer told me that it might just be bad gas so i since then have tried many brands of gas and everything from 87 to 93 octane so the gas is definately not the problem. I plan of bringing it back to the dealer on wednesday with my little boat on the back cuz thats when the pinging is the worse. That was the dealer can hear the pinging for sure.

I'm sorry buddy. I wish I was there.... Somtimes another eye is needed, just in case the obvious is missed. I just can't see spending 78.00 a flat rate hour at a dealership. YUK!! You've seemed to have cleaned or replaced just about everything that could be suspect. The last thing is probably the distributor. I'm exhausted by wracking my brain!!! I know how you must feel about right now!!! Get back to us with the "Professional" results... Talk with you later.....

bass,
I know how hard you've been trying to get rid of the pinging! Sounds like you have done everything possible.
I haven't heard of anything else to do regarding the Ranger; however, there was a TSB issued at some point covering certain Taurus/Sable 3.0L vulcans for which there is no hope left regarding pinging. Unfortunately, I don't have the text of the TSB but I remember that it involved shorting the Octane Adjust Plug.
This is out of my Ford Manual:
"The octane adjust (OCT ADJ) shorting bar is used to retard spark timing. Removal of the shorting bar from the in-line connector will typically retard spark three degrees.... DO NOT remove the shorting bar unless directed by a Technical Service Bulletin (TSB)."
Apparantly, some of the Taurus/Sable vulcans were not responding to anything else, so Ford issued the TSB to go ahead and remove the shorting bar and retard the timing another 3 degrees in those cases.
Like I said, the TSB was applicable to Taurus and Sables, not Rangers. But it might be something for you to think about.

One more thing related to my last post:
I've also read where the dealer first tries to reset the octane rating in the PCM to 87 octane. I don't know if this is part of "reflashing the PCM" that I've heard about, but apparantly what happens in some cases is that this particular setting in the PCM is improperly left blank from the factory and then defaults to a higher octane rating. This in turn requires higher octane gasoline to be used in those engines which makes them that much more prone to knocking.
If resetting the octane rating does not do the trick, then the ignition is retarded.

Hey guys...i recently found some new info. After having the dealer blow me off, i took my truck to a local trusty mechanic who checked my truck out and found that everything was working properly(other than a K&N air filter which he told me to remove ASAP). He then dug a little deeper and found a TSB very similar to the one Rock sent me a while back. He checked the TSB out with my truck and found that i do have the updated coil pack but he is not sure if i have the updated pcm. He says that ford began to build rangers with the new updated pcm's around 2/00 and my truck was built in 3/00. Since that is pretty close, there is a chance i dont have the updated pcm. Also, he says that the updated pcm's allow for octane adjust and when he tried to perform this, the pcm wouldnt allow it. So that must be the problem. The only thing is that the number stamped on my pcm doesnt match anything in fords database. It is one letter off of the closest match. So i dont know what the deal with that is. Replacing the pcm is the only other thing i can think of that can fix my problem so im going to the dealer in the morning tommorow and demand that i get a updated pcm under warranty.

Funny thing you mention the K&N filter....right after I bought my 2002 Ranger Edge, I installed the K&N, but realized that it didn't create the same seal as the factory one did. I drove around with the K&N for a while (I know, stupid mistake on my part), and began to notice the beloved sound of pinging coming from my 3.0 V6. Soon after, I replaced the K&N with a Fram. Twice now the dealer where I bought the truck has pretty much blown me off when I take my truck in for service, so I took it to another Ford dealership to have them look into the situation. They immediately verified the pinging and "retarded the timing". So far, so good...no more pinging, but only time will tell if it was a permanent or temporary fix. I wonder why Ford doesn't want to give us a straight answer on this issue.....???

Well, I spoke too soon. I thought that after retarding the timing, the pinging would have gone away. I hadn't heard it for 2 days, but on my way home from Cleveland today, it started chattering like crazy again. Does anyone have any ideas for me? 2 different Ford dealerships can't seem to fix my problem and I'm starting to get a little annoyed. Thanks......
