Ive looked into almost everything on getting my 91 Digi to idle properly but with no joy. She starts first time everytime but idles around 1k - 1,450. This happens when she is first started and will still happen when hot. Ive cleaned and checked breather pipes, cleaned icv with carb cleaner, put new plugs, leads, dizzy cap and rotor arm in but still no joy. Any help would be great.
