I think it went on limp mode. I push on the gas no response. Also the lights on the dash go crazy. I cannot go past two miles.

Good morning,

Is the check engine light on?

You can go to a parts store and have it checked for free. Once you know the code, then let me know so I can narrow down the area of failure.

Got it.

I attached a possible issue below. You need to verify the fuse listed for power on both sides.

If there is power, then looks like you have a failed PCM.
