Eddy Carb Tuning Help

Funny you said that. Yesterday I changed Valve covers on my 318. Did drivers side valve cover and put plug wires back on. Did Pass. side valve cover and went to start car and it fired right up but had a slight miss. Checked plug wires and forgot to put all 4 wires back on the Pass side. I thought I only screwed up 1 or 2 wires not all 4.
