Its a 2001 Windstar Sel. About last week i changed the spark plugs and wires. Now this morning when we went past 70mph the car jerked and the check engine light went on (only when you pass 70mph). Anyways the old plugs and wires were really worn do you think i need a new coil pack. Or was the gap on one of the plugs wrong. I am going to get the codes read later today but what do you think? Based on your knowledge, thanks~!
We've put like 300 miles on the car since i changed them so why would the problems show up now The plugs were pregapped by the way
