On Saturday I fitted new air filter, spark plugs, plug leads, dizzy cap, rotor button and distributor o-ring.
I also advanced the static timing to 10 degrees BTDC.
Throttle body was cleaned about 6 months ago.
Truck is running crisp, and pulling a lot stronger, and picks up better at low RPM.
No pinging. All seems good, except I now have a rough idle.
Truck is manual, and with AC off is idling at 650-750 rpm, but it's a tough idle.
Apply a little right foot and bring rooms up to 8-900 rpm, its still rough.
Runs well when off idle.
Thought I may have an unmetered air leak from intake hoses, but it seems ok.
What have I missed? Do I need to increase the idle? And if so, how?
