SL 450 missing when cold
I have a 1973 SL 450 with 180,000 miles on her. Just bought it. It has a serious miss on acceleration when cold. When the car gets above around 175-180 degrees the problem seems to go away. Car idles fine when cold. The people I bought it from, said it has been doing this for some time. I assume this ment more than 1 tank of gas. I have put injector cleaner in the fuel but have not run the tank out yet.
