Fouling spark plugs?
I've put 3 sets of R43TS plugs in my car in the last couple months, the car will run like a brand new car but after a couple days the idle gets rough and the car shakes a bit. It has a rebuilt quadrajet on it so it may have something to do with that. I live in Indiana so might I need a set of R45TS instead? It is a 305 HO(lol) and runs great when the plugs aren't fouled. If anyone has any suggestions please share them.

Forget about the heat range of the plugs and find out why they're fouling.

What do the plugs look like when you take them out?
A picture would be great.
