Re: hey guys. im back. My car is now officially screwed up.
You seems to have several electrical problems. I would check to see if your ground wires are correct, and that they are not coroded. I would also check for corosion in some wire harness.
As for you abcd... The bump could have caused a wire or harness to get loose somehow. as for bcd, have a compression test, should show up if you have such issues, but I doubt it cause what you have...
You said you dissassembled the throttle body, are you sure you connected the sensors correctly? and that you didn't messed up with any adjustement that I guess is there?
With the voltmeter, you might want to check from the ground of the battery to your car body, should be very close to 0V, same from battery to engine. Depending on the cars, some ground the motor to the body, other ground both body and motor directly to the battery. A faulty ground can cause tons of weird issues, including wrong sensor reading.
