Redo the throttle body adjustment.
Clear the codes.
Turn the car to "on", do not touch the accelerator. After 20 minutes, turn the car off and restart. See if the problem is gone with a TBA.

P1545 is throttle body controller malfunction code.

 

cant help with that code but it sounds like you upset the throttle control TP sensor when you disconnected the battery ( the engine would have shut down while the throttle flap was open and when you restarted the engine this would be recorded in the ECU so you need to rest the closed throttle position as the other guys have said ( I only give serious answers ),

 

Do I need to disconnect the battery? because I tried 3 different TBA method I found, but I dont hear no Clicking noise and it doesn't help.

 

ahh found the code cough, throttle valve sticking/tight, wiring fault, throttle control unit faulty im going for the first one

 

If you have a reader, clear the code and then do TBA without disconnecting the ECU.

If you don't have a reader, then disconnect the ECU for 30 minutes, reconnect then do the TBA. If that fails, check the wiring. If you are mechanically inclined, I have instructions for checking the wiring.

 

I believe I'm mechanically inclined... the instruction please, Tell me anything that you think will help and add steps if possible...I hope there is nothing that involve $$$ because my pocket is currently empty...

 

hey avant...i believe you right...but I can't understand what your trying to tell me, your telling me what wrong but...how can it resolve this issue?

 

any other ideas? First off, can someone tell me exactly what i caused? and is there any other way of fixing this?

 

BUSTED!!!

 

seriously i wasnt driving fast...maybe like 1 month ago that i hit the limiter and thats it...I was in the garage of my home what i accidently disconnected the battery when the ignition was on "on" but the motor wasnt running...like i know i screwed something up...but i want to the exactly what?

Let me tell you what i tried: 3 different method of the TBA and also I drove it 1 mile to see if it will re-adapt itself*ecu( the whole time i drove it, it would not let me go pass 20 miles per hour...if it hits 3000rpm it will just go back down to 400rpm all by itself)...
