I have a 99 ranger stepside
3.0 v6 flexfuel
When going uphill or anytime i try to accelerate when Im already moving I get a sound that I think sounds like a diesel engine and the engine is very slow to respond.

But every time I read about dieseling people are talking about trucks continuing to run after they are shut off.

So now I am wondering if this sound I hear is what is called pinging.

I run 87 and have read about running seafoam.

What do you think?

 

Run some seafoam. It wouldnt hurt. Im not sure about your 99 but i ran seafoam straight into the intake (vacuum line off of brake booster) I also have a 4.0, so i dont know.

 

Buy the seafoam spray and clean the throttle body and shoot the can into the intake.Does the same thing as going through brake booster.

 

how exactly does one shoot it?

 

Pull the intake hose off throttle body and put a rock or have someone hold the accelerator peddle down.Do this with truck off.Squirt the flap real good and clean it with a rag and a tooth brush if you like.Squirt at least half the can in all around the intake and let soak afew minutes.Start it up and it will smoke really bad for a while.When smoke dies down drive on street kind of agressivly for a bit to get the rest f smoke out.Pinging should be really reduced or gone now.If you like yuou can put the rest of can in and do it again.Really helps alot.

 

You keep saying spray or squirt, but the can of seafoam I bought is simply a twist off cap, there is no way to spray it.

 

"Deep creep" by seafoam is the same stuff as you find in the twist off cap....just in a spray can.

 

What Crunchy said:)

 

Oh and if you get the spray can,hold onto the straw.They sometimes fly off and you do not want that to go into the intake.

 

that would really "suck" lol

 

I suggest doing the Seafoam treatment as well but let the engine sit overnight so the product can soak into the carbon.
