How much did the new sensor set you back? Still have the old one? If you do I'd like to see the stuff you say won't come off of the element inside (take a pic). Just curious to see.

 

Okay, guys.....


PING IS GONE.


I have a pint of seafoam in my full tank, new MAFS, and 91 octane in the tank.

It's awesome. No ping whatsoever.


Thank you all for the help... It was alot cheaper this route!

 

sorry!

When I bought the new one I needed to give them my old one or I had to pay a ****ty core charge.

It was black on the element and wouldn't come off with the electrical cleaner.

 

Good to hear!

Eventually put a full tank of 87 in there and listen for pinging. There shouldn't be any or if there is, very very slight pinging.

 

My dad had that problem with the truck before he sold it to me. I just changed the plugs and wires so I'm going to switch back from about a year of running 89 and go back to 87 and see if there's any pinging. There's no reason you should have to run 89 in a Ranger just to get it to stop pining.

 

Agreed!

I ran a full tank of 91 with seafoam. When I refill tomorrow it will be 87. Ill keep everyone posted... I hope I don't hear anything. This truck runs great besides the prob I had.

 

yep. put in 87, no ping. sea foamed it and everything. now i can sell my truck if i had to and honestly say its in fine mechanical condition. sweeeet.

Thanks everyone.

 

Okay folks,

It's back...........It sort of sounds like lottery numbers being picked....like ping pong ***** in one of those machines......but very light and only when hard accelerating.

As posted earlier last year, I changed the MAF sensor but now something has changed... before, I could unplug the sensor and was still able to drive around but now when I unplug the sensor the truck will not start.

I am using 87 in the tank. I've noticed that it does NOT ping when I first start it in the morning and it only occurs when the vehicle is warmed up.

Also, I recleaned the MAF sensor as well as used the Seafoam treatment.

I am going to take off the EGR valve tonight to check that out and as well as check the spark plugs to see if they are all burning the same....

I read somewhere that some ranger owners have changed out their thermostats to another kind and that has helped with pinging.... ANY IDEAS?!?!?!??!

Please help me if you can with any ideas I am at my wits end with this stuff......considering going to the Ford dealership even though they will rape me financially.

Could the truck's computer system be out of whack and need to be completely set to defaults? I have no clue.


The truck idles fine and i have power when I accelerate..... My gas mileage isn't too great.... I get about 300 miles per tank at the moment. I think the truck runs fine except for that light ping pong sound coming from the engine..... I need help!

 

Okay...... I replaced the EGR valve and its sensor and the sound has decreased nearly 80%........ you think if I tried a step higher octane fuel the sound will completely disappear?

 

I sure hope you get this figured out ! I just recently got a 99 Ranger for work and almost everyday I'm shaking my head wondering WHY I made such a foolish mistake . I also have the pinging .

 

Believe me, I hope so too John. This is nuts...... The truck runs great save for the stupid tiny small ping like sound. Good news is I put 91 in it and I didn't hear even a single odd noise from the engine. Looks like I'm back in shape, if not, this thread will hear from me! It's time for me to get a motorcycle....I have the testing in a week then I'm saying goodbye to the truck.

 

I know this sounds silly , but with all the electronics on the vehicle. You need to check all the ground wires on the engine. you can check it and with engine running , see if there is any difference in voltage between the vehicle body and the motor. A 0.5 volt difference can mess up the sensors as to how they operate.
Hope this helps.

all i did was run some super and a can of 44k and my ping is gone

 

O2 sensor....you said the ping only happens when the truck is warm... when an engine is cold the 02 sensor is not in closed loop meaning its not sendig info to the pcm....check your 02 sensors

 

Where is the pings coming from because i have the ping too
