My 04 has 30,000 miles on it, I noticed that it had a popping noise when the car was ideling, I changed the plug to the champion platinum, unitl I get the NGK iridiums with better race wires with low resistance. I changed the plugs and the pop is still there after a good run. The car is currently running 15 psi boost on a stock ecu, it has a AGP waste gate and a turbo xs manuel boost controller. My question is, am I running to much boost? Will ig clear up with the better wires and plugs?

 

Never mind I had a brain fart moment, the gap was to big and I ran a can of combustion chamber cleaner in it and it runs stronger then before

 

What was your gap??
