Has anyone ever had one of these birds start when the weather is warm outside and not when it is cold? when it doesnt start everything is there for start, air,fuel,spark it just wont fire up. replaced a very nasty fuel filter. problems continues. on a warm day 55 or above she fires up as usual. rough idle in dr./reverse just fine in park and N. any suggestions?????? I have no cruse control now when it does start vacuum maybe??? any ideals to get bird on the road in the winter.
