Hey guys, i was driving down the freeway in traffic...and all of the sudden, my car starts shaking...it started to idle a little weird, and when i accelerate...the car shakes a lil and i lose A LOT of power...what do u guys think it mite be? spark plugs? vacuum leak? i took out one of the spark plug wires and it started the same, put that one back, took out another spark plug wire, and it started up even rougher? do u think thats the problem...im hoping it is...any other suggestions? thank you....
