98 Ranger 3.0 pings

My 98 Ranger 3.0 litre ( 70,000 miles) pings under moderate or greater acceleration even with premium gas with octance booster added. Any ideas as to the probable cause?

cool Re: 98 Ranger 3.0 pings

Have the dealer reflash the computer, but before you do that try disconnecting the battery for about 10 minutes and see if just a reset will help.

Re: 98 Ranger 3.0 pings

It pings because of the poor shape of the 3.0 combustion chamber.This is very well known. The shape and or poor combustion leads to very bad accumulation of soot which causes run on/pinging. It really helps to lower the engine temp as the 180 degree thermo mod is very popular. Did it to my 2001 3.0 and it cured my pinging. The seafoam treatment has good results too but have not done it myself. It is usually sucked in through the brake booster vac line and cleans out the chambers of soot. Somewhat tricky procedure but very popular.I would first try the 180 degree mod.

quick question- the seafoam treatment that you speak of what is this and do you know if this is something that can be done your self and if there is any web site describing the proceedure? Thanks

Re: 98 Ranger 3.0 pings

you can do it your self with the help of a friend to turn on and off the motor, mounted on the firewall is the break booster, driverside you should know what it looks like, bull the vac line out of the booster pour the seafoam in a big cup stick that hose as far down as it will go suck down half of it turn off the motor(it will be quick so have some one handy with you) and add the other half to your fule tank wait 15-30 min. turn on your truck and let all the white smoke come out. rev it every 5-10min up to 2000 rpm and let it sit again, wait till the smoke looks like its almost gone and go for a lil 10 min. drive! Its well worth the 7 bucks.

About the seafoam...mustang guys use it..alot. If your wondering about specifics, like where to put it and all that, try searching on a "mustang only" site. I'll bet you get 200 results back..
