When I start it and accelerate, it feels heavy as if it was choking. Then it picks up speed slowly. Anybody knows what it could be?

Truck drives fine until I get speed up, let it slow down a little, the try to get back to previous speed. It starts running rough, clunking sound, really scary. Help! What can/should I do?

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.

Occasionally slips out of overdrive causing tach to read several hundred rpms higher and “off” light on end of shifter blinks.

I can start my truck and it will idle fine in park or neutral
As soon as i put a load on it will start getting rough and stall out
In park it will idle for a bit till it gets warm then does the same as in drive
When i step on gas it will sometimes get the rpms to move but when i let off the gas the
Rpm stay up for a couple seconds then go down and stall
On diagnostics it will say im not getting a reading from crank phase sensor bank 2
Replaced sensor 3 times and still same thing

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.

My vehicle jerks and stalls while driving, usually when I speed it up. I've already chan the gas filter, the catalytic converter, the gas regulator, spark plugs, wiring and coils. Even though the jerking problem is not as worse as it used to be, the car still stalls. Can anyone help me please?

This light came on then my truck started driving really rough. It would sort of "jerk" forward when I took my foot off the peddle. Drove it 2 hours home like this but since then it as been fine (only been 4 days). Wondering whats wrong, read online that its probably the throttle body.

Cannot get truck to accelerate smoothly. When I apply throttle it hesitates and stumbles. I tested mass air flow harness and I get 6.1 volts at PCM wire.

It was working fine and the next day I used it I felt the truck heavy, it didn't have the normal acceleration, and then I realized it didn't have the power to go uphill, it went sluggishly and when the revolutions go up it started shuddering. With the scanner it showed errors P0755, P1747 and P0743, I was told it might be the gas pump, but the failure continues. It's a 2008 mexican Ford truck, 8 cilinders and 4.6L engine with automatic transmission.

The Climate control loses power sometimes the lights flicker on and off. It worked 4 days straight and the next day no power. I checked the fuse and it's fine. Any other fuses that may control the power to the climate control. Does the ECM have any control of the climate control module?

Got gas and then the problems started. Changed out 5 coil packs, all new plugs. New purge control valve. New fuel pump. Checked fuses and relay. Truck will start, rev up and then die. I hear a clicking sound near the kick panel fuse box just before it dies. Snap-On scanner is showing Code B10F1

The wrench symbol came on and the truck lost power and the a. C. Quit at the same time could this be a fuse issue

2009 ford f150 lariat 4x4 5.4 3v

First start after sitting overnight. Rpms go up the down right away to about 300 then back up to about 900. Put truck in reverse and truck stalls out. This does not occur every time. Does the same when I put in drive

Seems To Skip But Feels Like A Shudder Have Replaced Plugs , #1 coil fuel filter trans And differentel speed sensors gas cap had a p0500 code and emission code

Idels to high after its warm up...however you can hear it try to idle down but it will not...any help please...

When the truck goes over 4000 rpm the check engine light flickers for about 20 seconds, and at that point the truck loses acceleration and then it goes back to normal. The error codes I have are P0300, P0302 and P0306. Thanks for your help!

At the start, engine has a sound like hitting something, and after a couple minutes, warning low oil pressure, but back to the normal when I accelerate, sometimes appears the warning in high rpm (2500) and doesn't recover with the gas pedal. I have codes of crankshaft position sensor problems. I'm thinking to replace timing chain, but before start, any advices?

While driving at any speeds my truck shutters and jerks and also when I give it gas it jerks even harder sometimes. The shutter and jerking comes and goes but lately it seems to be getting worse.

When I drive at more than 55 mph it starts jerking and if I accelerate or step on the gas to overtake somebody it fails... Sometimes it takes a while to start doing this, but obviously it's not reliable if it happens every once in a while.

It starts normally and after a while the revolutions go up and down until it stabilizes again. Like 20 minutes afterwards it starts doing the same until it shuts off. The throttle body was cleaned, the spark plugs and cables were changed, but it does the same until shutting off.

Truck loses power while going down road and pushing on gas pedal don't help or do anything then truck dies

My truck starts normally, but as I'm accelerating it starts failing, the more I accelerate the more it fails, it loses power, the check enging light and a wrench indicator light come on, and while driving uphill it overheats. Please help me!

I can put truck in reverse it goes in gear but will only Rev up and won't move same thing when it's in 1st gear

So please and thank u to anyone that can help me and or give me some tips on what to do it would vary appriated

Replaced fuel pump but still get signs. It's a fuel pump. Think it's fuses. Loses power, Dogg's out, acts like transmission out, I have to manually change gears for it to try and go, backfires under hood also during all this. Then after a spell it runs fine. Unless gas is gone. Then it's hard to start have to add are lease half tank bang on it and constantly spray starting fluid with pedale to medal then after three cans starts. Does this Only when a quarter to none of gas in the tank left though. They say catalyst converter are clogged up is why ts doing that.

While driving the engine just lost power. When you depress the acclerator it was as you are not getting any fuel. I had it towed to a shop, the shop said they diagnosed the problem and it was the fuel pump, it was not getting the right amout of pressure. They replaced the fuel pump. When I picked up the truck it had a little rattle when changing gears, the mechanic said that the computer may needed to be reset! Drove the vehicle for a day and it shut down again with the same problems. Had to have it towed back to the shop.

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