My 2000 ford ranger pings while under a load then stops. 3.0 engine,auto.AC. I am under the impression that all or most modern vehicles have a anti detionation program in the computers. If not is the remedy to retard the ignition manually, or some other method? Thanks.

i take it that you do not have a check eng lite on!?
normally-you should never have to move the base timing-have you had the cam sensor/or drive replaced?
posssible an -egr problem-passages carboned up.will take some technical to diagnose & repair.
or could try clean the combustion chambers
a home version-buy a can of combustion chamber cleaner-can with a top/not a spray can.
locate a 'small' vacumm hose going some where-disconnect it 'temporarily'-have some one hold the eng. rpms at a high idle-dip the sucking end of this hose in to the can -a little at a time-over the period of say 2 min.untill the can is empty.

If I remember correctly you can't adjust the timing on your Ranger. It's distributorless.
I also seem to recall a dealer TSB that would reprogram the computer to reduce pinging. Might stop by your Ford dealer and just ask if it exists.
Hope that helps.

aandpdan;
you recall correctly. There were two tsbs, one was a repeat and more explicit. It mentions replacing the ign coil, and the powertrain module. I am beyond both the extended warranty, and the emmissions warranty, so if combustion chamber treatment does'nt work, I will check out prices of parts, and or going to Ford. Thanks for your help.

i do not think the ign coil could be causing the 'pining'
i do nt think the tsb stated 'replace' control module/pcm
most always- 'reprogram' pcm
a local ford dealer should do this for (est-only) 1-1 1/2 hour labor- est-$100/150
still possibility of pluged egr passages
'if' you are so inclined to try it-are you a mechanic at all?
i will try to shed some lite as to the process.
if not - let the ford guy diagnose / repair it

The TCB actually said replace the pcm [after road testing etc] with a revised pcm. However your plan for reprograming sounds interesting, since a new one is more than $400, but I am more of an oldfashened mech,bearings,rings, valves, so i am a little leary of computer stuff, but my youngest is a network engineer. Iam going to try the Techron trick and hope for some results. We'll see what happens. Thanks again.

I worked as a Tech for Ford for 18 years.. Using Fords (was the WDS system then) I could go into the PCM of your truck & adjust the timing curve for the fuel you were using (ethenol ,87 or 90 octane etc..) No different than reprogramming a different tire size,, axle ratio etc... Takes an experienced tech only a few mins... Roger

yes,you are corect!
things have 'moved forward', at a faster pace-than 'any one could predict.-(wds-book/shelved-not even opperational.)
current-is 'ids' updated-weekly/by 'ford'

'not' to argue, 'but' -'ford'-in most in every condition-'states -'reprogram'-not replace!
'i'm-'not 'a' driveability'guy,i could be wrong

Newtofta,, I have to agree with you on not replacing the PCM.. If it were to be replaced,, then the PCM & the instrument cluster & the GEM module & A.B.S. etc all have to be reprogrammed to accept the new PCM & the vehicles VIN has to maatch with all the modules or the truck will not start... The days of taking a used PCM & plugging it in ,in the backyard are long gone...cus it won't leave the backyard... Sorry Guys... Roger

I put i n two bottles of Techron in about four or five gallons of gas, and ran it down to near empty, and the pinging seems to have gone away. Thanks for all the advice, it was quite a forum.

'if' the problem 'stays' corrected,you might choose to upgrade the quality of gasoline that you are using.
that stated, 'i' for the past 20-years,use 'only'-'name brand'
stations-(mobile/chevron/exxon/shell-etc)!-i have 'never' had an injector problem/cloging-bad spray pattern)-)(i drive -only FORD vehicles-usualy-200,000+ miles before a new one-(but-"i"am a 'ford' tech.).
-just 'my'opinion on fuel.!
