Caravan starts & idles & runs ok at speed; code reader gives misfire on cyl 2 Took out plug 2 to find it coated with black soot. Put back in. Checked plug wire by replacing with a similar one. Ran same with continued pop and backfire? Replaced orig plug wire. Next day exchanged plugs between 2 and 4. Plug 2 this time was nice and gray like #4. Went to Advance to check their code reader against the one I borrowed and got the same code: misfrire on #2. Seemed to get worse on the 6 mile trip home. Help. Must be the coil pack?
have the same problem?
