450 SLC idle problem
I have a 1978 450 SLC with 118,000 miles. I am fighting with an idle problem. It runs fine and idles fine when cold but the idle gets rough and eratic when hot. I have changed plugs, wires, cap, and rotor. I have pulled the injuectors and cleaned but the holders aren't in the best shape. before I buy new injectors I would like some advice on this. Should I be looking at something else as the culprit? Any advice will be appreciated.
