I bouht the car 3 days ago, and filled it up with 87 gas last night (full tank) After That when I started the car the engine check light went on. So I took the car to autozone and had them check it. The computer said P0700, P1604. I found out later that my Chrysler should be filled up with 89 and that could have caused the engine error so I added an octane boost to it to see if it would stop the light from going on. (It didnt) I tried reseting the light and that didnt help either.

The probable cause from autozone says "ECM failure", "shorted or open circuit with transaxle" and "failure of transaxle controll module" What do you sugest I do because im not really sure what my next step should be since I didnt buy a waranty for the vehicle

Its got nothing to do with the fuel you used. There is a electrical problem in the transmission which could be caused by wiring, solenoids or ignition switch, unfortunately you need to do some pretty complicated wiring tests to be sure. Is there a lemon law in the state you bought the car in? I would definitely take it back to the dealer where you got it and complain. Let me know how you make out.
