OK, so i am driving normally and it will ping under a low gear. if i floor it, no more ping. i tried all grades of gasoline too. mechanically the engine runs perfect, no missing or shaking. it also makes a knock sound at 2k, like a rod mabey? i listened to it while holding it at 2k from the engine compartment and it sounded like it was coming from the cam area. i have no oil lights on or anything.. i have new oil in it too, 5w30 valvoline.

 

have you thought about a valve adjustment?
also put some lucas oil in it..

 

my valves don't make any noise, as far as i know. it is just pinging! anyone else have this problem? what would the lucus oil help?

 

Have you checked whether the ignition timing is set to spec?

 

no i didn't. my dad thinks it don;t advance like its suposed to and that its a knock sensor thats bad. what does that sensor do? i have ngr raceing plugs and new wires. i am throwing an engine light, iat sensor and the vss. how would the ignition time be off if it runs perfect? how can you check it? what is my dad refering to when he said advance mechizm not advanceing?

 

does anyone know how to hook up a timing light to check the ignition timing?

 

Inductive clip to #1 plug wire (closest to timing belt).

Red clip to + battery post.

Black clip to engine valve cover bolt.
