Ignition Problems?

This becomes more apparent if I stop the car to run errands, etc. get back in and start after 15 min or so. Car stumbles and flames out. I can restart, but it stumbles/surges until I make it back home. Usually, back road cruising is not a problem when the engine is under constant load. It seems to be a problem after it warms up and I'm in heavy traffic, or stop and then try to start it 10 - 15 min later.

Ignition coil issue perhaps? Any suggestions greatly appreciated.

Thanks,

Agreed, check float levels first.

Brian, first blow out your air bleeds. It's quick and it's easy. For instance, see this thread: This is new: stumbling/missing at idle/cruise speed
