My max pings in the summer with A?C on at 3500 rpm. I run 92 octane Shell V-Power fuel. 104k miles but I keep it tuned and ready. Help with my frustration needed. Sunoco 104 for $6.79/gl!!! Ouch!?

 

check for malfunction codes.

 

No codes present. CEL has not come on.

 

Try a differnt gas.

did you check for codes even though the light wasnt on?

the knock sensor code is silent, who knows maybe you need a new knock sensor for preventing pinging.

 

I did check for codes and none were present. I changed fuel type to Chevron premium and added a bottle of Lucas octane boost. Taking a trip this weekend and will see how it runs. Thanks for the input. KS at AutoZone list for 267 bones. I hear it is a bloody battle to change. It beats throwing out 1000 bones for labor though. Anybody got a better price they know of?

 

ebay, i just bought a KS for 62 with free shipping.

 

A thousand dollar for labor? WOW...I paid wholesale price for the knock sensor itself (OEM from Nissan dealer) and paid $250 for labor to change that and also the Vehicle Speed Sensor (which was like $60 I think, wholesale price again...)...but a thousand bucks? I hope you were just making things bigger than they really are.

 

Please explain how a new knock sensor would fix a pinging issue...

 

I would like to hear this as well.

 

actually theres a 44 bucks KS on ebay ryt now. btw i got mine for 52 bucks shipped. and it wasnt too hard to change. check out the KS thread and study it
