question for mechanics

[encore06]

My wife's 04 Grand Caravan has been missing lately, but today it seemed worse. Its noticeable while idling and when you give it a little gas. Hard pedal and it responds well. Later today the check engine light came on and I stopped by AutoZone and had it read. The sensor came back with a misfire in cylinder #4. I was told this could be a clogged injector, bad spark plug, or the coil pack. I'm thinking about replacing the plug and running some fuel injector through the tank, before I pay a mechanic to replace the injector or coil pack. Is this a reasonable route to take? Thanks

Thats what I would do,start small & work up.undo the battery to reset the codes on most cars

I'd put a new plug wire too, but almost bet on a coil failure.

New plugs and new wires. Wont be extremely expensive and work your way up.
Replaced all spark plugs and wires on one for a family friend that was reading the same problem except on cylider 1 i believe.
New plug and wire took care of it!

Thanks guys. We've had the van since 07/08 and have never changed any of the ignition components. 150,000+ miles. I think I'll start with the plugs and wires, then go from there.

Dont know for sure Carl, but id say that it dont have any plug wires. Probably a coil pack on each cylider. I would have a set of plugs put in it. Id say that will take care of it. If not then try a new coil.
