could be a number of possible problems causing it. I would start by having it scanned for codes if I were to guess though I would say the tps or throttle poisoning sensor went out


U already have the check engine light on, just take it to ur local auto parts place fof a free scan. It's probably related to throttle positioning sensor, throttle body or EGR valve
