My 02 started having issues starting after being parked over the weekend. After a few attempts it would start. Run fine. No power loss. The next day maybe just two times to start. So I installed new motor craft spark plugs. Bought from late model restoration. I bought a walbro 255 fuel pump. I installed the plugs one day. Started her up. Ran like always. Next day I put in fuel pump. Pretty strait forward. Started it up and ran like a new car! More power. Idled like brand new car. Drove great. Parked it Friday. Came to get it Monday and the car sounds like it is running on 3 cylinders. Real rough. Fuel pressure test with key on engine off. 70 psi. Start. Engine psi at 29 psi. Car has little smoke out tail pipes now. I have no check engine lights. While car was running I unplugged injectors and no change in motor. I unplugged 3 on driver side. I unplugged the fourth and and motor got a little worse. Any help is appreciated. The car has a bad idle. Any ideas on what to do?
