Intermittent not accelerating issue

My car is having intermittent acceleration issues. How to explain? On one start up it may accelerate just fine, then on the next start up it will barely move. It is also having battery discharge issues.

After I charged the battery, I started the car, and put it in reverse; it moved just fine. Then when I put back in the driveway, I didn't think it would move, so I stepped on the gas and I nearly rear-ended my truck. Now the battery is discharged again. The previous time I tried to drive it, it would not go while in drive.

Also, when in D3 or D4, and you try to accelerate from a dead stop, it hesitates in first gear. You have to hit the accelerator to the floor to get it to pick up speed so it will shift to the next gear. After it shifts to the next gear, it seems to drive just fine. Could it be a servo problem?
Do you
have the same problem?

The idea that there is a draw on the battery is likely tied into the issue. These vehicles are very dependent on the correct voltage to sensors and modules. If it is low, all kinds of things happen.

So, I need you to try three things. First, here is a link that explains how to locate and repair an electrical draw. Try to find and repair it. If you have questions or need help, let me know.

Next, I need you to check for diagnostic trouble codes that may point us in the right direction. Here is a link that explains how that is done. You don't need a scan tool for this vehicle.

The last test I need you to do is on the alternator. I need to know if it is producing enough voltage to recharge the battery and maintain a level system voltage. Here is a link for that. It is really simple to do:

Let me know what you find or if you need help.

Take care,
