Rough Idol when cold starting

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
