This morning I got in my wife's 2000 Dodge Caravan (2.4l 4cyl). It's been running fine. Well, it ran REAL rough, like a cylinder was misfiring. The check engine light came on then started blinking. I took it to Autozone and they put the computer analysis on it. It said it was a misfire in cylinder 2.
This made sense since it has 90,000m on it and the plugs were never changed.
I changed the plugs, and wires. It's better now, and the check engine went off (after disconnect and reconnect of the battery), but it's still running very rough, seemingly still missing, though not as bad.
Any ideas what else the problem might be. I realized after the fact that I didn't gap the plugs. Could this cause the problem?
Someone suggested the ignition coil or module, but I don't want to drop the $$$ for that unless I know that's what it is.
Thanks
