I drove it just enough so I could park it. I had my brother in law come and look at it (still in the parking space). After starting it again, it died only after about a minute. Then we let it sit and drove it again. The service engine soon light came on again and the S and M lights flashed again too. It also wouldn't drive well (had to apply a lot of gas to get it to move). It worked okay in reverse though. We think it might be in limp mode, but we aren't sure.
Also, my heat and a/c went out a couple of months ago, and I hadn't gotten around to getting them fixed yet. We know it has electrical problems; we tested the voltage on the power supply to the blower motor, and it was below 12. It needs new wiring.
We're having codes ran on it ASAP, but does anyone know what that could be/probably is? Thanks!
