Hi Folks,

I have a '93 Mercury Grand Marquis. I have just replaced the following: Plugs, Air Filter (K& N), Fuel Filter, Spark Plug Wires. The car was " stumbling" and ready to stall out at any time. That has all been resolved. It would also stall, sometimes, at idle. I also ran 1/2 can of Seafoam thru the PCV intake. The car has great power and starts well with good accelleration. The only problem is a somewhat rough idle. Could that be an IAC or something else? Thanks. MB
