No acceleration, WHISTLING SOUND (not squeal), intermittent CEL, only does it Gear.
96 Buick regal 3.8 automatic. I accelerated hard and the car just did not respond at all. It felt sluggish. Fell on its face as my dad would say. Immediately following this the engine light blinked intermittent short flashes for about a minute then went solid. After this the car whistles (not squeal) when you try to accelerate hard and no response. the CEL turned off the next day but you can make it come back on if you make the car do this whistle noise for a little while. then it will go off again later. You can't make the car make the noise in park or neutral though.The code is p0300 random misfire. Gas mileage down, and almost impossible to drive on highway. It has "chugged" a couple times for various lengths of time. Has new wires, plugs, and fuel filter. PLEASE any ideas???????
