it doesnt happen all the time just every once in a while, it's a nocking, and pinging sound, i have sreamen demon coil packs, mds wires, and ngk plugs, heat rang is a 5

 

you know with all the electonic upgrades you have to use high octain fuel... that will cause that sound sometimes.

 

i do i use 93 octain, thats the highest i can get around here

 

think i might now be getting anuff fuel

 

why would you need high octane fuel?

you shouldn't

 

Your ignition changes do not affect octane needs. There is a chance that with the higher voltage you are inducing crossfires, resulting in spark knock, especially if you have the wires bundled toghther. Check your wire & make sure they are routed according to the factory layout.

Heat range 5 means nothing much,as each company has its own way of labeling things. You need to have the proper plug heat range or you will definetely get preignition if the plugs are too hot, especually under load. Too cold and they will get fouled and misfire. If your car is basically stock, you will always get good results with OEM plugs.

You may, instead, have mechanical problems which will eventually get worse if not corrected. However, it is difficult to diagnose a problem from a distance, based on a written sound description.

 

i figured cause of the "chip" they require 93 oct. fuel.

 

Yes, but he didn't mention a chip. All he did was change coil packs, plugs & wires.

 

my bad forgot about that it's in my sig tho
