The truck is a 4.6L Triton v8 2WD 1999 F-150.
I had checked the truck for oil about 2 months ago and it seemed fine, but I checked it again about a month ago and it seemed very low. Around this same time, when I would accelerate the truck a little morethan usual, the engine would start to vibrate, like it was struggling, probably bc of low oil but I didnt know it at the time.
I did an oil change and changed the filter, checked for leaks, nothing. The same problem still persist.
it is like a hesitation when I give it throttle on the highway or when i try to accelerate hard from a light. If I accelerate slowly it drives just fine, but when it starts shaking and strainging when I was to go faster right away.
I just want to hear what people think is wrong and how I could fix it. thank you in advance.
I have the same problem . I was told that the torque converter clutch could be releasing due ta a bad signal, possibly from the throttle position sensor. I have the same problem .

There are many things that could cause hesitation on acceleration in a vehicle. It could be the fuel pump, the gas pump, fuel pump relay, or an electrical problem.
Could be a slight adjustment of the ( TPS ) throttle position sensor , or it may need to be replaced if it's causing a large hesitation during acceleration.

It could be a throttle linkeage problem or a transmission valve body problem.
Could be a bad throttle body assembly
A number of things can cause hesitation. There could be water or dirt in the tank. Also, it could be an ignition problem. Your ignition timing may be slightly off and your plugs are firing a split second off top dead center. This would account for the hesitation and subsequent bucking.
Your 1987 Astro might go full throttle when the engine is started because the throttle is sticking. This could also be a problem with the starter or the ignition hanging during the start.
The problem could be the Throttle Position Sensor (TPS) on the side of your throttle body. If the Rpm fluctuate when stopping also. Make note of this problem with the stalling. This is the most reason why it would stall. Just make sure the other problem In explained is there too before you go out and buy a new throttle body. I had the same problem with my colbolt and the throttle body cost was 255.00 that's with tax. So good luck.
While it could be an ignition problem, the most likely cuplrits are the fuel pump or the Throttle position sensor. Good Luck While it could be an ignition problem, the most likely cuplrits are the fuel pump or the Throttle position sensor. Good Luck
A couple of different things could cause hesitation in a 1999 Plymouth Breeze including bad spark plugs. There could also be an issue with the fuel filter.
If a 1995 Nissan Sentra will not shift out of first, there could be a problem with the throttle valve cable. The transmission could also be damaged.
