Code 71 & 72
Im getting codes for cylinder 1 and 2 misfire. I had the same problem before where I had code 73 misfire but then it went away and now i have code 71 & 72. The CEL light comes on and off randomly...like 1 week on 1 week off. What are the major causes of misfire? I'm thinking dizzy?...I changed the spark plugs already.
