hey, today i was driving the car and i was revving it and im pretty sure i didnt go past the red line. Then it just suddently stalled and stopped working. It took a few minutes to start up again but it started. The check engine light is on. Now the car stalls when idling and i've noticed that the intake is now blowing air rather then taking it in. Also the pistons are going up and down when its in idle. Please help and thanks. Also it has a short arm weapon R intake.
