I have been reading a bit on this fourm. Just found it today. It seems that ping is somewhat common to the 4.6? yes ? No?

I have a 4.6. It will ping when pulling a load, even with 91 oct every once in awhile. It drives me crazy. I feel like I am going to kill the truck.

Does this happen to everyone? Is there anything you can do about it?

Thanks for any information.

 

welcome to the pingers club, prettym uch everyone with a triton 4.6 is a member, includingme. Theres lots of ways to fix, just do a search on it. Dont worry if its just a ping it wont hurt anyhting just annoyin

 

If your 4.6 is pinging be careful. I burnt cylinder 4 and 7 intake valves and scored a cylinder Sat night . I was climbing a hill on the freeway and started to hear pinging so I let up on the gas but the "service engine soon" light started flashing, got off at the next offramp and the truck was missing. This was a 1999 with 54,000 miles and had a superchip. I'm not bagging on superchip because I loved the way the truck ran and yes I was running the best gas we can get here in California (Chevron). So be careful if your engine is pinging. Great shop put another 4.6 in for $2,800. Truck runs great again but I left the chip out.

I agree...pinging == bad bad deal! You'll end up melting a spark plug or worse like he said...torching your valves.
