Hi , all , my 2004 Vette has stock programming and premium gas , with that said I get a pinging when I get on it ? it comes in around the higher rpm range then goes away ? car only has 20,000 miles on it , any idea's what this could be ? kinda makes me nervous sometimes ? I had it to the dealer and they said it's ok ?????

i go with the dealers ,it's ok ! i heard some guys with zo6/zr1c/6's, etc.. if they are low on gas you can put in ,regular.!. of course may not even notice if your not racing...engine automatically adjusts !! i not sure any of us can feel 10>15 horsepower loss ? our 2006 ss monte carlo v8 and 2008 impala ss v8 run regular [87] all the time,monte has 100,000 miles on her... rkvette

you should never put anything below 91 octane in an LSX motor, it's just asking for trouble.

Change gas stations

Have a look at the plugs,

OEM Spark PLUG : 41-110

Have a tuner look at the tune

I run NGK tr55's but I have mods

Don't romp on this motor if it is Detonating

Luck !

Ok , so who makes a good tune for this car ? it is stock no mods ? would a hand held be best ?

absolutly not. do a mail order tune, Frost is a good provider of this service.

i would put money on it that it is your maf sensor. I had the same problem and wasnt throwing any codes had the dealer look at it and they said it was fine well BS. so i talked to a local tuner and he strongly recomended that i replace the maf. I replaced it with a oem maf and not a single ping since. he said that they just get lazy. it doesnt have to throw a code to be bad.. i would try cleaning it first if that doesnt work, try swapping it out. i know they are pricey so if you have a friend with a ls1 borrow his and take it for a ride if the ping is gone, replace it. just make sure you use oem though. aftermarket mafs or ported ones are junk
