I got a 1999 dakota 5.2L, seems to ping lots under load and heavy acceleration. can you set the timing on this? i know the comp does but what about the base timing?

 

No, timing cannot be changed without a tuner. And that isn't the real cause of the problem. A blown plenum gasket is a likely culprit, and/or carbon build up. I've seen Seafoam do magical things when it comes to removing carbon buildup and stop pinging.

 

Hows your plugs?

 

Thanks
I will look at the plenum, plugs are new
do i add the seafoam to the oil or in the gas tank
i know you can do both with it

 

You introduce it into the intake via a vacuum hose.

 

thanks i will try it

 

Define "Pinging" Can someone give a noob a description other than hearing a pinging sound.. any other symptoms?
