Spark plug question

ab · #1 (**permalink**) 10-26-2005, 05:53 PM

I am trying to get my 00 V8 to stop pinging. Done Bg44k, Combustion chamber spray, high octane... still there. Some of you recommend a cooler plug Denso IK22 (?) to stop the ping. What is the stock plug temp, what is the Denso IK22 temp and does the Denso plug effect any drivability? Thanks in advance.

The IK22 should only be used with the TRD 160 Thermostat.
The t-stat runs the truck abit cooler, thus richening the mixture to HELP reduce ping issues.
The Ik22 will help to dissipate heat better
Heat Dissipation in a spark plug. Of the 100% heat generated from the combustion, 20% is absorbed by fresh air from the intake of the following stroke. 58% of the heat is absorbed by the walls of the cylinder head which hold the spark plug in place. Twenty percent is absorbed by the insulator and side walls of the plug, the remaining 2% being absorbed by the spark plug wires.

Go to this page and see charts for complete description

I = Iridium Power Plug
K = Thread Size and Hex Size
22 = Heat Range

.
Make sure you have the stock air filter
My truck pinged even worse with the TRD filter and the K&N. Stock is best

I would try cleaning MAS Sensor in the intake to make sure it is not dirty as this can cause rough running and pinging in some cases.

Please update this thread and let us know if you do this and it works. That is the only thing I have not tried yet either. I am coming upon my first spark plug change and was thinking of going colder from the stock NGK BKR6EYA to a NGK BKR7E-11 to see if it helped with the rattling/pinging issue. Thanks

Sounds like it's running too lean. With all that stuff done it shouldn't ping. I got rid of some pinging during small throttle opening on an old Toyota by adjusting the throttle position sensor which was off some.

I also have a 2000 Tundra that pinged since new. Tried all that stuf with BG44k and cleaning MAF Sensor and premium gas and and and and. After I put on my JBA Headers it has gone away. Just my .02 cents.

My opinion

mostly city/ stop and go driving - Hotter plug
highway/ wide throttle - colder plugs

Yeah that's what I was afraid of. That is one of the reasons I have not switched to that colder plug yet. I do mostly stop and go city driving. I would like to get rid of that ping/rattle though. What is the worst that could happen by going to a colder plug even though you do mostly stop and go driving.
Thanks

are you guys sure you are hearing "ping" and not just the injector pump. The injector pump on these engines is notoriously noisy, especially under load.

Going on a colder plug on a stop and go city driving will eventually over time acummulate carbon built up. Which also act as a heat conductor causing you engine to ping even more plus carbon built up. Most tundra including mine has a ping on a little pass 1/4 to 1/2 gas pedal depress. Goes away if you open it more. Put it this way, if the pinging does not sound like marbles on a jar (literally) I would not worry about it to much.

My 2 cents

If you are still irritated by the ping, mix your gas 10 gallons premuim, the rest is regular. Keep your plug as stock heat range as possible.

My noise truly sounds like "marbles rattling in a jar" anytime I get on it to pass some body. It has been around off and on for the 3 years I have had the truck. I have made it disappear a few times by running octane booster and switching from Chevron to Shell gas while on a recent trip to higher elevations. I could not find any Chevron stations so I bought gas daily at the same Shell and the noise went away. It returned when I came back to sea level and switched back to Chevron. I don't know, I guess I will hold off on the colder plugs since from what you all are saying that will cause a problem in the end. Guess all I can do it live with it. I do still need to clean the throttle body and change the plugs anyway as I believe improper gapping could cause this as well.

"marbles rattling in a jar"

...is a problem, and it isn't directly gasoline related. I'd take the truck to the dealership and have them check for a defective knock sensor or other electronic part. The knock sensor's job is to prevent this spark knock.

Using higher octane gasoline is the wrong thing to do. Spark knock, or ping, in a modern engine is caused either by carbon build up in the combustion chamber or by a bad electronic control part. Or, the noise is actually something else. All that said, there are some engines designed for a very mild, harmless ping under heavy load...but I've never heard that from my Tundra.

Chevron says, "It is difficult for a driver to know whether a gasoline has the antiknock performance the engine requires when the engine is equipped with a knock sensor system. These systems, which temporarily retard spark timing to eliminate knocking, are installed on many late-model engines (see Chapter 5, Gasoline Engines). Retarding the spark reduces power and acceleration. The knock sensor responds so quickly that the driver never notices the knock. Loss of power and acceleration will be the only clues that the antiknock quality of the gasoline does not meet the vehicle's octane requirement.

"Using gasoline with an antiknock rating higher than that required to prevent knock or to prevent spark retardation by the knock sensor will not improve a vehicle's performance."

Thanks for the information. Yeah I have had it checked by the dealer many times, response is put higher octane gas in it. All our Tundras do it too. I will mention what you said and also what is your opinion on the MAF being bad here. During my monthly searching of posts related to this I saw where a guy had this replaced and it cured his problem. But this particular poster had driveability problems which I have never had. The truck never misses a beat. And the other thing is that mine is not consistent. And one of the times I had the dealer look at it they could not duplicate it and I couldn't either with the tech in the truck. A week later it is doing it again. Who knows. It's under an extended warranty anyway. I just find the whole thing embarrassing when I get on it when some one else is in the truck and they look at you like, what was that racket. After 3 years of people bitching about this I keep hoping one day I will sign on, come to TS, only to discover some simple cure that some one has found. Guess we will see.
Thanks

If the ping sounds truly like marbles in a jar then that is really bad!!!
Listen to KLS and take you rig to the dealer and have them check all the emissions sensor, throttle body and timing sensors. You might have a intermitting failure happening. If you stellarship dealer say again that every thing check out with in the parameters, at least ask and have them point out where all the sensors are that pertains to this issue and replace them your self.

baby pings that go away is normal -they sound like little ticking noise in series
loud pings that last between 2500 to 3500 RPM are not - sound like marbles in a glass jar in series are bad.

No amount of BKG, cleaners or gas can resolve that unless you go to the electronics.

Hope this helps
