Depending on weather car idles very rough/sputtering especially in the am for first drive.

40-60f and the car needs to reach about 175 on temp guage before you can drive it without very rough idle.

40 and below and the car barely starts. takes about 2 minutes to even fast idle. then even after reaches 175 very rough.

So far have replaced fuel distributor, checked injectors, checked hoses.

Any Ideas?

Thanks
