pinging 3.0

fordboi415 · Jan 18, 2009

I've got an 01 3.0 and I hear pinging witht these engines is common, what I want to know is how do I reduce it and or eliminate it

88gt · Jan 18, 2009

well, to start keep the engine properly tuned up with plugs, wires, air filter. they always help any engine. the 3.0 in my truck pings like hell all winter till they switch the fuelk back to summer blend. dunno why that is but the additives in the winter blend make my engine ping pretty bad. the only thing you can really to is fill at a major station lke amoco(BP fuels), chevron, or texaco. any other station i found makes the truck run like crap. thats about all you can do unless you have tons of money to get the spark curve retuned so that it doesn't ping.

mine did that w/ cheap gas or i found water in the fuel, new fuel filter took care of this problem when it was water. the only other thing i found that took care of it was nos brand octane booster, higher octane, or lucas fuel treatment. hope that helps.

ive heard a 180* thermostat will help the problem.

its well taken care of as far as maintenance goes and I only use shell vpower the 91 octane so fuel isn't the culprit

The K&N filter you are using passes a lot of dirt and oil. This dirt and oil will contaminate the MAF sensor element, causing it to measure less air flow than is actually flowing, ending up with a lean condition. The solution is to put the OEM filter and airbox back on, clean the MAF sensor, and reset the PCM.

well, since you arent using crappy fuel, it leaves the stock timing to be the culprit. if you had a distributor vehicle, you could adjust the timing so you dont ping anymore. that worked on my 2.9. since you have a coil pack. you'd need to have the computer reprogrammed witha new spark curve so that it wont ping. but like i said earlier, the winter fuel makes my motor ping a lot whereas the summer fuel doesn't almost at all. the fuell additives are to blame there to...so more or less there isnt a thing you can do for it and i wouldn't suggest octane boost. the octane of the fuel has nothing to do with it sice your running 91 octane already

whoa whoa whoa! the truck was running and not pinging with that timing curve when it left the factory why on EARTH would he have to have it retuned now? there should be absolutely no reason why he cant run 87 octane and the factory reccomended spark advance with no pinging. if he cant, then something needs to be repaired or replaced...not covered up with band-aids.

carbon build up is a very likely culprit. hitting the motor with seafoam is your best bet...but in extreme cases, opening the engine is your only option. lean conditions can also cause pinging. the 3.0 is injectorly challenged from the factory as it is. things like a weak fuel pump, pressure regulator, or clogged injectors or filters will cause it to starve and ping. vacuum leaks can also cause lean conditions.

If he does what I suggested, and the pinging stops, this will confirm that the K&N was the culprit, which you have admitted will pass more dirt and oil than the OEM paper filter!!!!

My first Ranger was a '99 3.0 that would ping on the summer gas we get here. (Different parts of the country get different gas at different times.) I took it to the dealer several times on warranty and it would be okay for a few weeks then start doing it again. I finally gave up and just ran 91 in it in the summer.
Try disconnecting the battery for about 10 minutes to reset the computer.
Also a malfunctioning EGR valve will cause pinging.

EGR pinging?

would pinging, which i've found is also described as valve clatter?,does it sound like a clatter or rattling when accelerating? or under load, as in towing? my truck has always done this...

if it is involved with the egr valve, here's my story..

when i bought my truck the guys said that the check engine light was on and it was because of the emissions system... so i had it plugged in and sure enough "egr flow insufficient", before buying a new egr valve, I cleaned the throttle body (upon advice from advance discount auto merchant), and the MAF sensor, and reset computer to see if check engine light would come back on... it did..

so I bought the EGR valve, and replaced it. reset computer, light comes back on, same "egr flow insufficient"...

so, what do I do?

Wicked_Sludge · Jan 19, 2009

pinging and valve trane noises are two different things. pinging is often heard under high load/low RPM. downshifting will usually make it go away except in extreme cases.

a faulty EGR system will cause pinging. you most likely have a bad DPFE...a very common problem.

Wicked_Sludge · Jan 19, 2009

here ya go bob, i snapped these tonight just for you buddy!

i installed my K&N on 5-24-05 at 112,638 miles with 116.2 hours on my hourmeter. today im at 132,983 miles with 872.4 hours. i have not cleaned anything upstream of the filter since installation...so what you see is all there is. i have vacuumed the sand out of the dirty side of the filter box after spinning dohnuts on the beach.

granted i only have about 20,000 miles on the filter. but thats 20,000 miles of towing and off-roading. if it was going to pass dirt and/or oil onto the MAF it would have done it (or at least STARTED to do it) by now.

no this isnt a definitive result. yes it is A result. not every K&N is going to cause problems in every truck and they can and are employed successfully on occasion.

Be shure your using platnum plugs and gaped correctly, this would cure pinging and hesation fron idle to about 2,600 rpm.

FL_forlife33 · Feb 2, 2009

I finally solved my "EGR flow insufficient" problem by replacing the DPFE sensor with the newer plastic one... no more check engine light... but the pinging is still there.. i'm still confused as to the difference of pinging and knocking.. my engine makes this noise most audible at high load, low rpm... i replaced the plugs and wires myself, using platinum plugs i got from advance discount auto specific to my truck, those should already be gapped correctly no?

is there anything else that would cause this? it's so annoying
