rough running 2004

Hi,

2004 Sebring Convert. 4,000 miles on it. Whenever the car is not driven for a
few days (two or three) it runs very rough, engine skips sputters for a few
minutes. This has happened a number of times, and NOT on the same tank of gas.
My other cars (Subaru, Honda, Pontiac) can be left for 7 to 10 days like in an
airport parking lot and they just start up with no problem. Any ideas???

Fuel system not holding pressure is a possibility. Bad fuel pump or related
issue. Needs a visit to dealer. Was your area getting tons of rain? Could
be ignition issue. By the way if you have the 2.7 engine be sure to get oil
and filter changes at least every 3000 miles. It needs good oil or sludges
up and keep your receipts as proof of maintenence.

 

Isn't. He said it runs roughly for *several minutes* upon startup after
sitting for an extended period. Loss of fuel system pressure causes
extended crank time before fireup, but not several minutes of rough
running.

In any event, as a 2004, it's gotta be under warranty.

 

Mine does the same thing ('04 'vert w/28k miles). Please let us know what
you find out. My Saturns used to do the same thing after they sat for a
week or so. I just assumed that condensation built up and it took a few
minutes to burn off/evaporate.

 

Yes that bothered me and that is why I also suggested the ignition system
and a trip to the dealer.

 

1. Moisture
2. Something draining your battery and causing things to operate on the
hairy edge until the alternator juices the battery for a while and
restores things. Marginal battery voltage can cause all kinds of very
strange symptoms. I had this on a Ford I once owned (don't ask!). Most
ECU's have a monitor that will shut things down, or refuse to start the
car if battery voltage is not within spec however when it is real close
things are unpredictable.

You might try measuring battery voltage before you start the car and after
the car has sat for a couple of days.
