Hey-
I have read articles on the many possabilites on how to fix the 4.6 pinging. I experience the pinging when 1) under hard acceleratoin 2) highway speed, especially going up hills at 70+
I have heard of cleaning sensors, cleaning throttle body, removing K*N filter, etc...
Please, someone tell me what i can do to fix this. I have run 104+, fuel injector cleaner, etc and i always run 91 octane. I shouldnt have to do this. Please post ways to fix this. Any tips or instructions are appreciated.
- Patrick

 

anyone...?

I posted a similar thread asking for some info for pinging in my 02 screw, 4 days now, no reply! I guess you need to be one of the "good ole boys" for someone to respond. Don't get me wrong this site is great for info, but if your not one of the 'Buds" they dont want to talk to you. I hope you get some advice, my 02, 1400 miles, is at the dealer today and until they straighten it out!!!! I didn't shell out $$$$ to listen to the "ping band" and ruin an engine in a year!!!

 

Hi,
I just want to say that even though I understand your frustration I don't think that you're right. After monitoring the forums for around two years I can say that there is no simple solution for the issue. If you search the forum for "pinging" you'll understand what I mean: tons(!) of posts. There are a couple of threads with a summary. But again, each truck is special. That's why you did not get a reply.

First of all fix it! Do not run high octane or use any snake oil!

Almost all pinging in the 4.6's is carbon build up and egr concerns.

Find a dealer that sells BG products and get 2 cans of BG 44k this stuff is the best carbon remover on the planet. If you cant find that run Techron for 2-3 tank fulls of REGULAR gas. In addition you want to remove your egr valve and clean it and any passageways that are related to the egr SYSTEM. Also make sure the vacuum lines to the egr are not cracked. The last this is once you do all of this replace your 02 sensors.

Good luck!

 

what are BG products?

Using the Search function would be the best way to get the info you are looking for. I think AB is correct on why you haven't got the info you are looking for. Speaking only for myself, I saw your post on the first day, but haven't had time to reply, espeically since all the info I could possible share with you is already on the site.

But to summarize, my '98 had a pinging problem and the only solution was a custom programmed chip. I had exhausted everything else, so it was either spend $275 on a chip or live with it.

Once you do a search, let me know if there is anything else I could help you with. I figured I spent about 6 months trying to do the simple, inexpensive fixes first.

 

mcrpoisson- I don't think this is a "good ole boys" or "bud" issue at all. My guess on why you haven't gotten a response is because no one knows how to help you.

A brand new truck with 1400 miles can't have carbon build-up and it is unlikely that a sensor was bad to begin with or would have failed this early. Working with the dealer is probably your only option, espescially since you have a warranty.

From what I've seen on other boards, it is fairly common for people to not respond to a question when that information is already published on the site. It's not because existing members don't want to help someone new, its that there really isn't a need to re-type the same info over and over.

Hope the dealer fixes your problem quickly.

 

Hi,
Here is the page http://www.bgprod.com/autofuel.html
and you can buy it here

The only thing I heard is that you must use it when you're ready to burn the whole tank of gas in 1-2 days. Then change oil (as usual with those things)
Alex.

 

I think the reason your not getting the response you want is that there isn't a clear cut answer that can be suggested that will correct your problem in every single case, and what suggestions can be made are made on a weekly basis. As Ted said, I think your best bet is to get a chip if you want to fix it for the long run. I'm planning on ordering one as soon as I get the money (and don't have to spend it on something else!) Other than that, possible fixes are the MAF sensor, DPFE sensor, spark plugs, carbon buildup, clogged up throttle body, clogged up EGR, etc. Just really depends on the state of tune with your truck. At 1400 miles I think the answer is a chip. If your at 100,000 miles you might look into doing a little tuning up first. Personally, I think all of our problems are atleast partially computer related. In my case, the temperature is the determining factor as far as if it pings or not. Pings like hell in the cold, not a problem whatsoever when it's warm, which again leads me to believe my problem is with the computer. (if it was the state of tune I think it would ping atleast to some extent all the time.) Oh an btw, there's no charges, initiations, or other dues for the good ol' boy club... Come on in.. The hazing gets a little outta hand every now and then, but you can handle it!

 

Green_98,

Another option is it to take it to the dealer and request them to do an upper intake cleaning (through the injection system) to remove the carbon ($100-150). My brother had it done to his 98 4.6 and it eliminated the pinging and improved performance.

Mcrpoisson,
I would think that your truck is too new to have any problems from excess carbon build-up. I would have the dealer look at the EGR system.

For both:
I run Chevron gasoline in my 01 5.4. It has techron in it which helps to keep carbon build-up to a minimum.

 

on the contrary you do NOT want to burn a whole tank in 1-2 days with BG 44k You want to do a lot of short to medium trips so that the chemical can sit on the valves and such to break up the carbon.

You only want to run the tank through fast if you are only trying to clean the injectors.

You are correct however that it is a good idea to change the oil once that treated tank of gas is gone.

Yes a truck with just 1400 miles on it is much too young for carbon build up. Most likely a computer problem or something was installed incorrectly at the factory. And yes a sensor can be bad at 1400 miles.

Good luck-

 

hey guys thanks for the info my trucks got 49,500 miles on the 4.6 and it runs perfect like i said but just pings under hard accelleration or 70mph+. I think ill pull the throttle body apart and spray some gumout into the engine that will be held at high idle by someone else.
ill also check into the intake clenaing mentioned above. THanks again. any more suggestions welcome---

 

I'm in the same boat with you. I think we talked about this before. I have to agree 100% with what you just posted. I think it's mostly the tuning of the engine and the sensors. Is yours only on cold days at higher RPMS (3000+)?
Mine use to ping worse than it does but after the TB cleaning I did back in the spring along with a new DPFE and EGR it has helped some. I guess in winter time I will have to run 89 again (hate to, shouldn't have to). I wish we could figure this out.

You do not have to be in the good ole boys club but.... it does help......... Would you like to join? Well, just put n ya chaw of the good stuff, throw on your bibs and boots and come on in. Sorry I just take things the wrong way and to extremes sometimes.

 

DO NOT USE Gummout Carb cleaner! Only use "INTAKE" cleaner!! These Fords have a plastic coating on the intakes that the carb cleaner will ruin!!

Remember I said the EGR System not just the EGR valve and/or the DPFE sensor. If you read back posts you will see that the EGR Valve is almost never bad BUT the 4.6 has 2 passage ways for the EGR System that are smaller than the 5.4 and they clog up very early in the 4.6's life, especially if you frequently run a higher octane fuel. They are very easy to clean out.

When your EGR system gets clogged you do not get enough EGR durring hard acceleration/load therfore the engine runs hotter than normal which in turn causes ping. In addition because the engine runs a little hotter (Internally not the whole engine) if you do have carbon build up it will glow and cause even more detonation. (Ping)

Even though the use of an EGR system has been around for over 10 years it is still very missunderstood.

Have fun-
