Baylinermike Posted September 15, 2015 Report Share Posted September 15, 2015 I'm getting a ping when I floor it. I don't usually beat on it. I floored it yesterday and noticed a ping. I went to the gas station and filled up with 93 octane. I usually always put 93 octane in it. But gas was a few weeks old in the tank so I filled up. Drove it about 30 miles, then floored it again. Ping is still there... My first thought was "gas station isn't really selling 93". A few days ago my battery died from running my radio too long (fool). I jump started the truck and it wouldn't idle for about 5 minutes (kept stalling unless I kept it at about 900 rpms. I figured the tps went out of wack. It idles fine now, but noticed a ping when I floor it. Is there anything else I can do? Quote Link to comment Share on other sites More sharing options...

70chevy03ss Posted September 15, 2015 Report Share Posted September 15, 2015 Did you fill up with shell 93? Also when is the last time you changed your fuel filter and also cleaned ur throttle body and maf? Do you have a tune?

kaze_v8 Posted September 15, 2015 Report Share Posted September 15, 2015 Spark plugs? Quote Link to comment Share on other sites More sharing options...
EXGM Posted September 15, 2015 Report Share Posted September 15, 2015 Yeah, has it ever been tuned up? If you have over 100K your due. Heck mine only has 53K and I am going to change the plugs and wires soon... they are 10 years old at this point and see it preventative maintenance.....

Baylinermike Posted September 15, 2015 Author Report Share Posted September 15, 2015 No tune. Only MOD is a CAI. Has 170k. Just bought it a few months ago. No idea last tune up. Will try all of the above. Are autolites the best plugs to run? Quote Link to comment Share on other sites More sharing options...

70chevy03ss Posted September 15, 2015 Report Share Posted September 15, 2015 ac delco and Taylor 409 plugs Quote Link to comment Share on other sites More sharing options...
desrtrat Posted September 16, 2015 Report Share Posted September 16, 2015 after 170k on it, it could be just some carbon build up. even running top notch gas you never know what the last owner ran. IMO- i would run 1/3 can of seafoam thu the intake..(follow directions) and the rest put in fuel tank, and see if that helps. cheep @ about $8 at most parts stores.. good luck Quote Link to comment Share on other sites More sharing options...
EXGM Posted September 16, 2015 Report Share Posted September 16, 2015 Auto lite are cheap plugs you get what you pay for. Spend the extra and get ac delco. Quote Link to comment Share on other sites More sharing options...
