Acceleration problems: really doggy and won't
Check/change air filter.
Check/change spark plugs & plug wires. The wires can be check with an OHM meter, and the specs for the resistance in the manual. So can the ignition coils.
Change fuel filter...easy.
Last, if you have scanner...check MAF(mass air flow sensor) for operating specs...5g/sec at idle to 300gal/sec+ @ 3,000 RPM.

I have a PONTIAIC 05 grand prix GTP my information center says anti theft is disabled after installing and new ignition switch also the information is all in Spanish I need english
Why did you install a new ignition switch ? Lock cylinder part or electrical ?
You have no idea of the complexity of the electronic's on this vehicle ,your best bet take it to a qualified repair shop.
The body control module (BCM) uses the discrete ignition switch inputs ignition 1, ignition 3 and crank to distinguish the correct power mode. Once the BCM has determined the power mode selected by the vehicle operator it will energize the Ignition relay, Run relay and retained accessory power (RAP) relay, depending on which power mode is selected.
Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits.

My 2005 grand prix battery died, so I went to
Do you know how to voltage drop automotive electrical circuit's using a DMM - digital multi-meter ? Checking main power feed to fuse box etc.... loose connection , bad positive feed cable etc ..
Do you know what wiring diagrams are ? Electrical distribution diagrams ?
Electric Testing Techniques You Need to Know

Enter vehicle info. year , make , model an engine size. Under system click on electrical distribution then under subsystem click on power distribution . Click the search button then the blue link's . test the circuit's . Plus knowing how the systems work would be good . When you turn the key to start it send a low voltage signal to the BCM - body control module . The BCM sends a message to the PCM/ECM - engine computer to energize the starter relay . A lot of complex electronic's an electrical systems involved .

2005 grand am shifter problem
The shifter button on the shifter is released when you start up your car and step on the brake pedal. If you are having an intermittent problem, you may be having a shifter release solenoid issue. the shift solenoid is part of the brake light switch system so the problem can also be in the brake switch. If you do not know how to check it out, I would bring it to a reputable repair shop and have them check it out for you.
