Hello '
I have a 99 winstar 3.0 When I put the lower grade gas in, it pings real bad, but when I use high grade gas the ping goes away for the most part. any idea why this happens and is there away to stop it.

I think the dealership shop can adjust your vehicle so that it will run on reg gas. Unless the engine is designed to run on only premium. Check with the dealer or qaulified shop.

Adjusting the timing may help. It may or may not affect the gas mileage.

This vehicle is designed to run on regular gas

If it is pinging on regular, you may be experiencing "octane creep"
It may have developed carbon deposits on the pistons that increase the compression inside the cylinders, leading to premature ignition in the combustion chamber

The higher octane gas has a higher anti-knock rating for higher compression engines, so it works better in an engine with these deposits

The best/surest way to fix it is open it up and clean the pistons and combustion chambers

Sometimes you can clean the carbon out w/o taking apart the engine by using GM's Top Engine Cleaner, or Sea Foam

A word of warning if you use these products, as part of the cleaning process, your van will emit an awful lot of smoke when it's started back up
It's supposed to, but i just wanted to warn you
You might not want to do it upwind from your neighbor's garden party
....and you might want to do it when it's kinda dark out

Timing is non-adjustable on most Ford vehicles. Sometimes pings are cause by MAF sensor. The Hot and Cold wires get dirty when the air filters are not
changed. This being said the Baro reading gets off so fuel trims are effected. Like slickshift said carbon is another cause of pings. EGR problems?

Isn't the timming adjustable by reprogramming the computer?

Technically you would be correct, but that's a looooooong way to go with the EEC-IV
And it might address the symptoms (or not)
But not the problem

It's in reality not that do-able

It's not unusual to have to reflash the computer at the dealer. I did this with my 01 Sable 3.0L Vulcan engine to get rid of pinging.... it was a known and common problem. Check the tsb's for your vehicle. Otherwise, like others said, you may have excessive carbon deposits in the cylinders.
