I have a 1994 Chrysler New Yorker with a 3.5 v6.
The engine started running rough off and on and now runs bad constantly.

I need to know what to check.. The engine has 132000 miles on it. I replaced the plugs and plug wires at about 80000 miles.

What do I need to check? I was going to start with plug wires/plugs. could I have a fuel problem or a bad coil pack?

Give it a full major tune-up-check the charging system and battery then comeback
