I want to do a combustion chamber cleaning. I'm getting some pinging at WOT. Can't stand that!! Probably some carbon on my pistons I'm thinking. Car is an 06 with 31000 on it and I got it at 27500, but I'm the 3rd owner, and no telling what the PO's did, with driving habits and all.
I saw a thread on another forum where a Chevy tech said to removes plugs, fill cylinders with GM top end cleaner, and let it sit over night. Next day crank engine to expel fluid, reinstall plugs, start and let idle for 20 min. Then shut down and change oil n filter. Then go driving!! He said has done this technique with over 50 LS motors and has had perfect results. Only thing is they don't make the GM top end cleaner anymore. I found some new AC delco inj and chamber cleaner at Chevy today, but I'm not sure. Bottle says for pressurized use in fuel rail. I've also heard the Mopar Combustion chamber cleaner is another one being used since the GM product is no longer available.
Anyway I wanted to ask for some opinions if I may.
