i got back from a drive to the smog place, and my car started acting up so i couldn't smog it (the idle started pulsing but now i got a new tps) the issue is when i got it back home, a day later i tried to start it and it won't idle, it bucks after i manage to start it up and i need to press the gas to keep it alive. It has a surging idle and the whole car shakes...any ideas what this could be? im still looking around to find out what it could be...i noticed my sensor on the top of my radiator broke would that cause a problem?
