pinging with my 2.7 WHY?
132,000 miles on the 2.7, and whenever im going up a grade, my truck will begin to lose power, but it also pings very badly. if i shift down to 4th, i have higher RPMs but im able to maintain speed up the incline, and the pinging usually goes away, but not always.
my question is why am I pinging? i dont have an S/C and i run 89 octane. I've run 91 and still gotten pinging on inclines? is there some cause for this that i can fix or what????

My guess would be something wrong with the knock sensor. I have heard that you can test them by tapping something near them while the engine is running. If it is working correctly then the engine will sputter a little.

i second the seafoam idea....i think that will cure your problem....
as gwhayduke said...carbon builded up will get real hot and cause your pre det/pinging....so the sea foam make fix the problem all together...
