Can't get my '98 4L to stop pinging, just when I think i've solved the problem it comes back. This is my second ranger in a row to give me unsolvable pinging problems.
It was fun finding star security bits to clean MAF sensors, blasting throttlebody cleaners into throttle bodies, annoying the neighbors with Seafoam treatments smokeshows, spritzing gallons of WD40 into door assemblies to get the door ajar light to shut off ...
But I think i've had enough, just test drove an '02 Dodge ram 4x4 4.7L, I'm sure it'll come with it's own set of problems, but it didn't ping on the test drive.
I'm a bit nostalgic, drove a '90 STX 2.9L from 2001 to 2006, a '97 2.3L from 2006 - 2007 which also pinged, and now the '98.
My Ranger quit pinging completely when I started using hi-test gasoline. I know it cost more but when I figured out the cost per mile, it was just over one cent per mile more than regular. There are a lot of people on this site who will say that regular is best but my truck has 190,500 miles, doesn't burn oil and still gets 23-25 MPG (3.0, 5-spd). Those numbers are hard to dispute. With Hi-test gasoline, it has noticeably more power. I can pull hills in 5th gear that would require a downshift on regular gas and best of all, no pinging.
I have an engine "shunt" on my 90-2.3-EFI & it's so the engine can use the lower octane fuel & I'm wondering if something like that exists on the 4.0's?
And my 4-banger Ranger also pings slightly when climbing hills so I'd say it's the E10 or whatever the Gov's blending now.
And if it were not for the mucho-rust on this Ranger it would be the best!

Reason: wording
I didn't see any mention of the EGR system. If the EGR tube or passages are plugged partially, or fully, it can cause pinging. If the EGR valve is sticky or the pintle is clogged, same thing.

You will love the mileage on the Dodge, be prepared to more of your wallet into the pump, unless you get real lucky. Get the peeps with the Dodge to fill it up then go for a longish (30 mile) test drive , fill it back up and figure the mileage out. I think you will like your Ranger more after that.
If his truck has a continous ping then his milage probably already sux. Now is the Ram going to get better milage? In the short term I would imagine so, In the long term?
With gas where I live at over $3.70 a gallon full size trucks and SUV's are staying on the lot in droves. With unemployment hovering at around 7.8% they can't give them away.
Now if I could get a 4banger 4x4 Ranger...
Oh, foolish me, this is the last year of the Ranger as Ford upsizes... brialliant!
