It sounds like the ECU has gone into the protective "limp mode". Get the codes read at the parts store to see if anything shows up.


thank you, side note to this. after I had the car towed home last night I drove it around some and it ran fine, could this still be the ECU?


The ECU reads the sensors and controls the engine accordingly. It could be the ECU or it could be one of the dozens of things that it reads. Get the codes read to see what is going on before replacing parts.
