It started losing power it would not go over fifty five mph and now it wont over thirty five mph. I checked the fuel pressure, key on it was 30 psi and dropped off instantly. I replaced the fuel pump, the pressure is back where it should be. I replaced the plugs and wires, the plugs were fouled and the wires at the coil were corroded. It drive okay cold, but as it warms up it starts surging and bogs out during acceleration. I only have a p0449 code that pops up. I attached a scanner and while running I get a cylinder misfire on Cylinders one and two.
What could be causing this?
