Please help cant rid myself of detonation noise? cant seem to solve it
ok i had a noise goin on im my car which i belive to be detonation i had it scaned with hp tuners and in fact i had some KR. so i cleaned the maf and it went almost completely away.
so figureing the car is new to me ive owned for about 2 months, lemme give it a tune up sense i dunno when it had one last. i did seafoam treatment,NGK tr55's gapped .055,msd wires,fuel filter, pcv valve, and RP 10w30 for oil change, but after my tune up this noise that disapeared came back full force. my previous plugs were denso iridiums, and they all had a light brown colored seemed just right.
so i cant figure out what the hell is goin on. i get ping/clanging noise down low below 1500rpms when i tap the gas and detonation ping noise above 4500 WOT. im am gettin down to my last nerve with this **** please someone gimme an idea what else could i check to get rid of detnation why could it be happening.

lol well man we are in the same boat, its driving me nuts, if u find anything lemme know, im starting to narrow it down to possibly 1 cylinder oiling from im thinking leaking valve guides/seals. but im not sure yet. im gonna run my car in speed density mode and see if it helps or not eliminating the maf as the problem and then gonna have my mechainc look at it and good a compression and valve seal test, then possibly use my warrenty if i can. but if u find somehtin please lemme know

this may be a stupid comment but is your A.I.R. gasket from the pipe to the manifolds good? did you RTV it? are you sure that all the spark plugs are in and the wires are on tight.

anyway im am thinking it might be the gas ive used occasionally at the cheapy station by me i just sat in traffic for 1.5 hours tonite so i had alot fo time to think, when i had the issue before i was always runnin cheapy station gas, then the night i went to get it scanned with hptuners 1st i put 15 bucks of sunoco in and when i got there about 45 min drive away the noise wasant as loud or easy to make happen but still there, after that i ran sunoco for about the next week and i cleaned my maf at this point the sound was gone but on my way home i ran seafoam this time,
the next day the past sat. i ran it to "E" then i happen to fill it up at the cheapy station cause it was cheap. well i only drove it 1/3 mile home on back roads, the next day io went outside and did my tune up to discover the noisees were back,
well today i thought about it and it adds up to ther gas i think, so i got 1/2 tank left and i will fill it again with sunoco and see if it mystically disapears again, i really hope this is it, lol would make me so happy, especailly after seeing a 2700 dollar drop in my insurance today lol, idd be a happy camper man. well ill let u know what happens ill prolly fill up in 2 days from now

"Some customers may comment on a mild to severe engine ping (commonly referred to as spark knock), usually worse during acceleration and/or an illuminated MIL. Upon investigation, the technician may find DTC P0332 set.
This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. This condition is more apparent on vehicles in which customers frequently wash the engine compartmentReplace the rear bank knock sensor and build a dam (wall) around the sensor using RTV to divert water away from the sensor"
Not sure if this your problem but it's something to look into.Good luck!
