do any of you guys get pinging on your GS4? it usually happens to me when i accelerate after coasting, not from a dead start.

 

where is the pinging coming from? do you hear it when you are standing outside? cheap gas over the years will cause a pinging.

 

Maybe it's not premium, I haven't really experienced it, but I have read that lower octane can cause some pinging.

 

I use premium 91 and hear it sometimes while driving. I think it happens more when the car has been running for extended times.

 

Sounds like bad gas. Try some octane booster.

 

got enuff coolant or oil... check that first

 

Usually cheap gas is the culprit. I recommend using only premium fuel. Also, get a BG induction flush...that should clear out a lot of the carbon build up in your intake system.

 

i use premium for ten years no pinging yet also check oil weight

 

Its your K&N filter. Get rid of that garbage, get a stock air filter and clean your MAF sensor with CRC MAF cleaner.

 

same issue on my 430... I want to pull a plug to see if it really is ping... I only run 91.

IF, its the filter its CAUSE THEY over-oiled it not cause of the filter. cant help that you, (OCH) cant read and follow directions on how oil a airfilter. i have run my k&n on my gs430 for over 2 years NO PROBLEMS, NO ISSUES, NO CELS, NOTHING.

OP its probably gas....cheap gas. did u recently add some 85? or 87? whaetevr you'll have there? we lucky enough to have 93 here lol

 

I only had my K&N filter for a year, I never oiled it. Just because you don't have issues doesn't mean it can't cause issues. I suggest you inspect your MAF, you will see buildup on it.

 

well, directions state u should oil it so maybe you shoulda. i have checked and rechecked my MAF no oil residue.

 

i've always used 91 gas. regardless if i use shell, 76, or chevron, i still get the occasional pinging. i clean my maf out twice a year, and make sure the k&n is not over oiled too. maybe i will try an oem filter and see what happens.
