When accelerating it boggs out at to 32 RPMs it falls down stalls out

When is saturated it is that adds up to about 3200 RPMs then it falls down if you keep it to the floor or pump the pedal and eventually rev up and get through the bargaining stage sometimes it won't even stall out are running just fine most of the time it will bogg

Acceleration loss under load
Ford F-150 2005 F150 5.4 3valve 100000 miles
Has power with overdrive off but hesitates and Boggs down when going up hill with overdrive on and acts sluggish when cruising at low speeds with overdrive on. When you step on the gas halfway to the floor or more it Boggs way down before accelerating. I have replaced all 8 coils all 8 spark plugs fuel filter both evap valves and the fuel pump control module and cleaned the mass airflow sensor and dumped fuel system cleaner in the tank.

Sounds like the cat I'm going threw the exact same problem right now trying to figure out how to bypass the o2 sensor on the cat minna a 5.4 01 ford expedition
I went through this problem for about 9 months. Replaced icm, computer, disputer, coils, plugs , wires, tps, maf, egr , fuel pressure regulator,. Last thing replaced o2 sensor fixed the total thing. If I was to start over I would get the air right, o2 sensors and maf. Then check fuel pressure, and go from there. Go to a mechanic that can read the obd1 computer to diaganose it better. Good luck

If you have the 4R70E or W transmission there’s an issue with the design of the drum in the transmission and the valves sticking in the valve body. They make a better designed drum to fix the problem.
CommentMy pick up does not accelerate
Ford F-150 1998 140000 miles
It started with jerks while driving; when starting gold y vibrates and then it normalizes. While driving it losed power as if choking a little, but now it got worse. It chokes while accelerating and sounds as if exploding, when I let go it keeps driving; if I accelerate again it does the same but it doesn't stall. If I turn it off for 5 seconds it works for 10 minutes and then it fails again. I alreadi cleaned the injectors, changed spark plugs, air filter, fuel filter, fuel pump, coils and their sensors. I've already had this problem for a year and they can't solve it, yesterday I scanned it and had air sensor error, but changing it didn't fix it.

It has a broken cable, an electrician can find it and fixit. I had the same problem for almost a year
Which cable are you referring to? Is it electrical or vacuum?
Search in youtube how to perform a maf sensor test
It sounds like the issue I had with my 2008 5.4l engine. I replaced spark plugs and coils. Finally it ended up being the VCT solenoid. I got my power back and it runs great.
Have you tried changing fuel pump module, ford ground wires should be cleaned tightened up fender well grounds all of them. Make aground wire ,ground strap ect. Ground firewall to the bracket on alt.
CommentNo power when accelerating

If I push the gas too much feels like it wants to bog out if I don't gas it as much seems fine ??
