Pinging on acceleration on a flat ground

I have a pinging problem which when i take it to a mechanic the sound goes away .. i think it's a complete gas system cleaner i put in to clean the gas lines,injectore ,trottle body and injectors.. the sound goes away after a few seconds and doesn't make it going up hills so i hope it's normal.. i also hear a grinding sound when i make turns but had my cv joints and suspension checked and nothing broken or wrong.. has anyone had these problems too and know what it is.. thank you

    the grinding may be worn out brake pads or a wheel bearing problem, have you checked these? Are you sure this is a ping? what do you mean it goes away after a few seconds? more info on the ping, also how many miles on this beauty?

SOURCE: 94 Geo Prizm CV or driveaxle?

on this type of vehichle, you have two axles in the front; one going to each side. Chances are that the boot at the axle joint was torn and that is why you are having problem. In teh past people used to replace the boot, this day and age its actually cheaper to replace the axle. So you would need to replace that side of the axle (the half shaft).

2003 chrysler concord nocks pings left side

Knocking and pinging are two separate things. "Knocking" usually refers to the sound an engine makes when internal mechanical parts, such as piston rod bearings or connecting rod bearings, begin to wear and cause a deep "knock, knock, knock" sound during engine rotation. "Pinging" refers to the tapping sound you get upon acceleration, either when using fuel that is to loo octane for the vehicle, or when static timing is set too far advanced, or when the cylinder heads are overheating due to clogged water channels or thin oil.
If you are hearing KNOCKING on the left side, it is likely time for an engine rebuild. If you are hearing PINGING, you may need a better grade of fuel, or you are way overdue for either an oil change or a major tune-up.

I have a 2009 Nissan Altima and when I stop I hear a pinging noise from engine but when I accelerate it goes away. When I put it in park the noise goes away. It only happens when I am stopped at a light...

Take to a mechanic. My guess is you have either a hydraulic valve lifter problem or if the car has not been properly maintained you could have signs of engine bearing problems. Double-check your Engine oil level immediately. If it is low or not even on the dipstick, hopefully that is the problem and you have caught the problem early enough. Good luckl

Why does my 98 expedition make a pinging noise at 25 to 35 mph then goes away

this noise is detonation. It is an uncontrolled untimed ignition from hot spots in the combustion chamber igniting an incorrect air/fuel mixture. IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder. Fuel quality is important so if you are using a standard grade fuel( 89-91 octane rated) fill with a premium fuel with a higher fuel octane rating . Give a miss to E- fuel mixtures

Clacking noise when going up steep hills

What you may be hearing is called "octane ping". It occurs when the engine is under heavy load and the fuel does not have enough octane to efficiently run the engine. Older engines like yours were often run on premium gasoline to avoid this. However, if you do not have the clacking when accelerating on level ground and only have it on the steeper hills, it is not necessary to spend more money for mid-grade of premium fuel. Only if the engine makes the noise under normal operation is this advised. A little octane ping in those situations will not hurt the engine. But, if you need the peace of mind, and to ensure that the clacking IS octane related, I would try one tank of premium and retest the engine of a hill you know causes the problem to see if it goes away.

Could be engine "ping" from bad octane in your gas. Try a gas treatment like STP octane boost. If is still does this, check your oil, bad rods or low oil can make this sound too. Try Rislone for oil treatment or Slick 50.

I get a ping when i accelareat in my 94 gmc 350 vandura

Low octain fuel or the rings on your 20 year old engine may be wearing and you age getting oil in the combustion chamber, effectively lowering the octain.

Have your mechanic do a compression test on your engine and wee what he or she thinks.

Dodge Ram 2500 engine ping

Your ignition timing may have advanced too far. Or it is now where it should be and is making more cylinder pressure during combustion causing the gasoline to ignite to early causing detonation or ping.

Make sure the ignition timing is correct. If it is try better fuel meaning the octane rating.

If you can go up to the next octane level. For example if you are using 87 go to 89 and see if it goes away. 3 of my wife's last cars a 1986 Honda Prelude, 2000 Neon, and a 2003 Neon had some ping under medium to hard acceleration. She switched to 89 octane and the ping went away completely in each vehicle. Each of the vehicle had a good deal of miles on them.

The 2003 Neon has 75000 miles on it now and runs great on 89 octane. About a year ago I tried 87 Octane in her car and the ping came right back.
