my 850 sounds ruff when I start it. it also takes off slow when I start off from
What is your question?
a stop point, or when I slow down while driving. I have to mash the gas almost all the way down to get it to respond properly to the peddle, and that's when the engine sounds normal. and its only at higher speeds. both the check engine lights, and the asc light comes on flashing when I start the car, but then they go away from time to time while driving I put 2 brand new MAFS in, I CHANGED THE SPARK PLUGS, put a brand new fuel pump in. I have not changed the fuel filter yet nor have I changed the rotors ,or distributor caps for the engine, or changed the spark plug wires yet. do you know what it may be or where should I start?
