Bucking/Surging Epidemic

[_N8_]

did you recently purchase the part? I’m trying to find anew and having zero luck. Thanks -

The post above his shows purchase date vs arrival. Looks like about a month.

i have had the new EGR valve installed a couple of days now. I have noticed a 3+ mpg gain. It doesn’t surprise me as this is part of the emission system stuff, but wow never thought it would be this much. It may even continue to climb. Here’s hoping…..

This Forum is the best!!! I’ve only had intermittent surging nothing that has ever been too bad. When I first bought the truck I installed a Mishimoto catch can I wonder if this helped my emissions system stay cleaner? I have a 2019 w/50k miles recently have noticed the ranger is a little more sluggish. So I’m going to change sensor and purchased 3 (2 for back up) I paid 22$ through Varsity Ford. Thanks again for all the information shared on this site the stealership will never help like this site.

Just thought I'd throw my experience in here....

I am experiencing what I thought was similar to what is described in this thread: when I take off at a slow start (for example after pulling out of the drive and driving through the neighborhood) going about 20-25 it shifts up to 4th gear and then does this jerking (bucking) action like it's wanting to shift up to 5th but won't. So, I figured what they hey and ordered an EGR valve and replaced it.

RESULTS: Same issue. No change. Keep in mind I only have 13.5k miles so mine may not have enough miles to be clogged/affected like some others.

I will say the job was super simple. Just pull the old clamps back and pull the hose off. It was a beast trying to get the longer hose off the metal piping but several tugs eventually got it off. Put the new one on (I bought part # that included hoses) and twist the clamp retainers off and re-attached wire harness.

Oh well - was a $45 part that may prevent something worse in the future

Add me to the list those who have fixed their bucking issue.

First off, thanks to a fellow poster on this site who had a spare EGR valve and sold it and shipped it to me. Nice to know there are folks around that still help others out. I sincerely appreciate his efforts as it took time from his end to get it to me.

I see how many can change this part out is 30 minutes or less. I can honestly say the actual part swap out too me less than 30 minutes and it was an easy repair to make. However, I'd like to nominate myself for taking the most time to do this simple task. I didn't need to find flashlight batteries as a prior poster but did something that took way more time. I dropped the darn wrench into the engine bay when removing the one and only bolt to get the bracket off.

I search for this stupid wrench forever looking down from the top. Couldn't see it. Tried going underneath, couldn't see it. Took off the driver side tire and the plastic "shrouds" - still couldn't find it. Finally took a flashlight and put it on a string and lowered it into the lower parts of the engine bay. Finally found where it was and then it was just a matter of time go under the truck and get something long enough to jiggle the wrench free which I finally did. Put everything back together. Total repair time, a little over 2 hours or so.

Results - drove the truck for maybe 10 miles. Went down a flat road at 25 mph and the truck stayed in 6th gear (usually would go into 7th when I had the issues). Feathered the throttle and nothing. No bucking/surging or whatever the issue is being called. I saw the perfect description of this problem somewhere. It was like driving a manual tranny and being in too high a gear and hitting the gas causing the vehicle to buck until you would downshift into a lower gear.

No more hard shifts, the whole truck drives smoother, idles better and no more hard shifts. Truck, and me, will be putting on 750 or so miles on it in the next week and if I have any issues, they will show up in this time period.

Thanks again for all the help, and special thanks to a forum member who sold me his extra brand new part. A lifesaver.

This thread has me thinking of doing this part change even though I don't experience this. Does anyone think this will have to be a repeatable purchase? I'm curious on why they are going bad in the first place.

Glad it worked out for you Mark. As I and others have stated, (maybe after your 700+ mile test) if this resolved your issue, make sure you take it into your dealer and let them know and have them let Corporate know.

Yeah. As mentioned somewhere, the dealer is't bad and I hope they have done what they think is right. I know the ownership and they are good people as well.

I have been in contact with the service manager throughout this event. I was, and am still upset that Ford wouldn't have taken care of what they thought the issue was as the truck was 200 miles over the 60,000 drive train warranty. I had this issue well before I brought it in, just didn't get it there in time.

But for sure, I'll be in touch with them when I return

If that didn't do it for you, you might consider getting a forscan adapter so you can clear the transmission and pcm adaptive values. The sensor helped with mine, but there was still some funniness with it. If I clear the transmission adaptive tables and the PCM (I think, I'd have to double check) and follow the Ford procedure for relearn, (trans up to temp, shifts 1-8 below 2000 rpm) it gets better.

At 39k I seem to have a problem that showed up. When driving at a steady speed of 25 to 35 mph it feels like the torque converter locks and unlocks over and over. I can feel the vehicle bucking though not violently. Mentioned it to the dealer when I had an oil change and they tried to tell me this is acceptable and others are experiencing it also.

However, I've also noticed at times when starting out at times the engine rpm seems to rise and fall kink of fluttering. So I don't think it's the converter. Anyone else experience this? I am taking it in for service the end of this week. I really hope they don't try to tell me this is acceptable.

Maybe I jumped around and didn't read through here thoroughly, but has this been resolved with the 2022? That part number LB5Z-9J433-B doesn't list 2022 as a compatible model year.

If I may need it in the future I'd like to get one on order now for how cheap it is. This way when I need it in a few years it's lost in my garage somewhere.

Once again, this forum was amazing!!! I have had the same issue so many in here complained about. I ordered the EGR Valve listed in this thread from the One and Only Benny and Levittown ford parts. It was back ordered but they got it here as soon as they could.
It did take about 15 mins to install. _N8_ The pics were very helpful and needed. The only thing y'all did not provide was the third hand needed to hold the light.
I installed the new value. Took a quick test drive and my 2019 Ranger drove like new. It was GREAT!! Can't thank each of you for the work and information. No way the dealer would have done this job for only $47 much less in 15 mins.
Thanks again and party on!

And people who post back that the issue got resolved doing such are just as valuable to the forums. It erks me when someone is always ready to come in a forum and ask for help and then disappear - leaving others to wonder.
So thank you!

I am so glad someone pointed me here. For the most part I'm happy with my Ranger but I've owned enough new vehicles to be tired of hearing "that's acceptable" from a dealer. Trying to sweep it under the rug hoping you'll give up.

My mind was made up that if they couldn't fix it I was going to trade it in on another make of vehicle.

In one week the symptoms have gone from barely noticeable to what is going on with this truck.

This morning I took my 2019 Lariat in for this problem. Talking to the service manager I told him about this post and the EGR solution. Fortunately for me he owns a Ranger and agreed on the cause and solution. Unfortunately they did not have the part and it should be in next week.

He told me it took him over a year to find the solution when his did the bucking. He said Ford thinks it has something to do with gas because those running 91 octane seem to have the problem around 40k while those running regular have it earlier. I don't think mine has seen 87 octane more then 7 tanks, I always ran the higher octane.

It looks like Ford knows about the problem now.

 

[Mark W]

I have only used regular gas and my problems started at over 58,000 miles.
