I have the pinging problem that has been addressed several times in the forum. My 99 Ranger 4x4 3.0 automatic w/81k pings under load, but the ping diminishes at higher rpm's. I've replaced the air filter and spark plugs (autolite douple-p....I know, some don't care for these), and have even used higher octane fuel. the pinging will subside for a tank or so, then return. I had similar ping in an '87 f-150 I-6 4 speed I used to have. I just learned to deal with it.

My question is how do I clean the MAF, the IAC and similar shade-tree jobs that I can do. I've given myself a migrane attempting to find all this on my own. I'm on a limited budget, just as many of you guys are. I would appreciate any and all help. Thanks!

PS. I only use my Ranger for running my rural mail route of 100 miles/day (60-70 % dirt roads...if you wanna call it dirt) and bouncing around the pasture. All B.S. aside, I have had the very best experience with fords(on my 4th). Had a goat...too much body noise and fed it too much gas - rolling it on the interstate was the best thing that happened to me in 2001. After that, shelled out the cash and bought, at that time, my dream truck! A brand new shiney red Z-71 ext. cab with all the bells and whistles. For such a "tough" truck, I had to do a crap-load of maint.!!!! traded it for a 2002 S-duty......been exstatic ever since! (thank you superchips) BTW...wifey drives the s-duty

 

Try this:

Cleaning Your MAF Sensor

 

Thanks!!!! wonder why that didn't come up on my search?? Anyway, you saved me a lot of time. As my dad always says, "Thanks 'till you're better paid"!!

 

You're welcome. Let us know if it helps the pinging.

 

Rolling on the interstate doesn't sound like fun. I hope you didn't get hurt.

 

Only very slight pinging at low rpm's under load such as a good hill. Now if I could find some decent gas around here....thanks guys!!

My left shoulder warns of impending weather now, but it's cool. I got lucky. Passenger side....fubared. Driver side...not a scratch. I'll try to post pics. thanks for the concern!

 

Ay! TxColt;
Now that I'm experienced in this area, I can pass this info along you're question:

My question is how do I clean the MAF, the IAC and similar shade-tree jobs that I can do.

These 3 items are what I've done so far: On my 90 Ranger 2.3L, there may be some differances than w/ your 3.0: I Simply removed the 4 screws holding on my Throttle Body. Both the IAC + TPS were connected to it. The IAC is a long valve w/ a 3 wire connect coming from it + 2 screws hold it in place onto the body. The TPS has a 4 wire connect also w/ 2 screws holding it in place. The MAF; located on the filter housing, has a 4 wire connect + 4 screws holding it in place. Go to Sticky: Tech Info for more.
