Yes. Buy a Kia. Just kidding..never do that, you'll regret it for the rest of your life. Sounds like an ECU problem. Remove the ECU and have it rebuilt. Prior to that, open it up and check for leaking capacitors. Also a suspect would be the fuel pump ECU, you can have the 12v Mod done to it before spending 100 bucks on a rebuild. GL.

I noticed the vacuum line on the intake is broke off, that may fix the sputtering but haven't been able to find a new one, but if thee was a best or something n the blower wouldn't that keep the a/c from working too? Cuz the a/c blows ice cold
