whats up guys im having a bit of an issue.

last night at 65F degrees about 2000 meters elevation i was driving and went to pass a car and floored it WOT and at around high 4k rpm the car suddenly lost all power and felt like an experience of when you miss a gear in a manual car.

at first i thought it was a transmission issue but noticed it was still shifting fine except it was sluggish as hell. no smoke no noise, was able to drive home but couldn't even keep up with traffic. at idle it sounds like a tractor barely stays on idling roughly 500rpm.

what can it be? spark plug, wires, coil pack , sensors?
