mrjhansc Posted August 13 Report Share Posted August 13 Hello all, I replaced the fuel pump this morning on my 2019 Edge SEL, with the 2.0, it is running better but still staggers and jerks when accelerating. It’s not throwing any codes, no engine light or anything. I replaced the coil packs at 70,000, plugs, MAS and air filters 3 months ago. It has 103,000 miles on it. any suggestions for what I can look at to correct this issue? all advice and help is appreciated. Quote Link to comment Share on other sites More sharing options...

What are you using to scan for codes? Quote Link to comment Share on other sites More sharing options...
garycrist Posted August 14 Report Share Posted August 14 Spark plugs breaking down under load will cause that problem.How old and what kind gap etc.? Boosted engines "loves dem plugs". 1 Quote Link to comment Share on other sites More sharing options...

The last time the transmission was serviced was at 62,000 miles, about 3 years ago, the torque converter went out and Ford wasn't too pleased that it had to cover the rebuild on the extended warranty. If there were an issue with the programming wouldn't that throw a code of some sort? Quote Link to comment Share on other sites More sharing options...

I ran through it several cycles, no codes in the queue and nothing pulls up under new codes. Not even a check engine light or the dreaded wrench light.

I recommend that you use Forscan - yes, I've had other reputable scanners show no codes only to find that there was stored codes using Forscan. The symptoms you describe there's bound to be codes stored. 1 Quote Link to comment Share on other sites More sharing options...

garycrist Posted August 14 Report Share Posted August 14 Why did you replace the plugs to begin with? Did it jerk/stagger before the plugs were replaced? Try lowering the gap down to .28 It might be you are "blowing out" the spark with a wide gap. What was the gap on the old plugs? Quote Link to comment Share on other sites More sharing options...

I think it only does OBD-II codes, and not PCM or other modules. I used one like it, Torque on my cell phone, but not until I used Forscan on a laptop did I get the maturing/pending codes or eventually the ones that set the powertrain fault. Mine went from slightly jerky (like the TSB...under 35 mph, I was setting up an appointment to get it programmed, if it met the criteria, on my own dime) to a whole slew of various solenoid and friction codes, some are E which is used for 5-8th, some are the frctions used for other gears, and that is how it was behaving, freewheeling above 4th gear unless I slowed down. The p0771 from OBD-II was the only one I ever saw on just a code reader (it was 110 degrees outside and I was dying so I just took camera shots of the screen): 1 1 Quote Link to comment Share on other sites More sharing options...

I honestly don’t remember what the gap was on the old ones. I hadn’t thought about that. At this point I’m willing to try anything. Quote Link to comment Share on other sites More sharing options...

A good starting point in the diagnostics is knowing the stored fault codes - the misfiring/staggering potential causes go beyond bad spark plugs.

Waiting on the delivery of the FORscan cables to run the diagnostic this weekend. Like I said, it hasn't thrown any codes previously, no engine light or anything.

Change the oil every 5,000 miles, synthetic, not sure of the filter as I rely on the oil change place to take care of that. Quote Link to comment Share on other sites More sharing options...

I'll have the cables by this weekend, already downloaded the software. I am hoping that the learning curve isn't too steep when dealing with it.

mrjhansc Posted August 26 Author Report Share Posted August 26 Finally got a code to pop up… looks like the torque converter clutch selonoid. from what I’m discovering, there’s been a lot of issues with this in 2019-2021 models. Anyone else have the staggering and jerking issue resolved with this replacement? Quote Link to comment Share on other sites More sharing options...
