Had same problem last winter. The intake upper and lower manifold gaskets might be bad and need replacement. They can when engine is cold. When engine warms up, gaskets (o-rings) expand and seal and stop leak. You are also probably experiencing a lean condition as well. You can also check the wire harness going into the ec Located above the engine going into the firewall. Check the green-white wire located on the far right (looking at it from the front of the car) and see if there are any kinks or broken wire. this is a common spot for the wire to break and cause misfires on number 1 cylinder. Wire harness is piece of crap
