^^like you said, check timing, then change to higher octane fuel and after that if it still does it seafoam da' puppy!!!!!!!!
as long as no egr codes are present ftw!!

well everyone has added useful info and I'd run higher octane and if your timing iswhere you say it's at, you shouldn't be having this issue...what everyone has missed is one key factor that causes detonation,all ready mentioned are#1 inadequate octane fuel, incorrect timing and the third not mentioned......=on your engine when such occurs/ pinging on a higher mileage 5.0..it is often a result of elevated cumbustion chamber temps which is caused by an increase in compression as a result of excessive carbon build up on top of the pistons/ cumbustion chamber = corrected by using a good induction clean / seafoam treatment...I like BG induction cleans.....also I'd run a koer test and make sure there are no EGR codes... a malfunctioning egr systemwill contribute to pinging in that the egr introduces exhaust gases into the cylinders to quench the combustion process to lower chamber temps to reduce pinging..hope all this helps

100%, but probably a bit over analysized. If he screwed with the timing thats probably the case. If you havent, then check the previously mentioned statement.

..sometimes I wonder if the dealership life would be more relaxing...I go from working on a bmw to a toyota and back to a classic car each week[&:]
