Has anyone ever solved there 3FE rough/fast idle yet. I had my intake system decarboned and my fuel system cleaned. New plugs, wires, cap & rotor.
Checked for vacume leaks with starting fluid (Found None) Replaced the vacume modulator.
Mine runs much better but when i start it in the morning the idle goes right to 1500rpm then about 10 seconds later it will drop to 1100 to 1050rpm. It will stay there for 4 or 5 miles then in gear it will drop to around 950,
after it has warmed up fully it will be around 700rpm. My questions are, is this normal at start up, and will it hurt my drive line shifting at a high idle.
Thank for the help
