Took a nice 50 mile ride in the car the other day. Went no more than 10 miles into the ride and stopped at a stop sign and the car would not idle for crap. It sounded like it was looping. Adjusted the idle to bring it up and it still did not idle properly.
The car has plenty of power on takeoff and cruise.
Once I go home I replace the fuel filter same condition.
Checked all of the wires going to the coil and HT lead, everything was secure and no broken or chafed wires.
Pulled each plug wire off while idling the engine did not show any faults.
Replaced the distributor cap and still idles rough. Engine will start almost first turn of the key when warm. With old or new cap.
I am thinking maybe condensor or coil going bad.
I am running a Weber 32/35, Mild street cam, 25D Distributor from Advance Dist.
Since then I took the carb top off and removed the jets, idle mixture screw and cleaned everything with carb cleaner. Started the car back up and it still ran rough. Adjusted the car and still running rough. Took off spark plug wires again and all were good except 3. When3 was taken off no change in idle. Pulled plugs and they all look while or lean. Adjusted mixture to richen and still rough idle. Checked dizzy and it was a little loose and could be turned by hand. Re-set timing at about 17 BDC still has rough idle and will not maintain good idle. It seems to want to go up and down.
Any ideas?
