I have a 2004 Hyundai Elantra GT with 28,000 miles. It is a 5 speed.

About two weeks ago I filled my gas tank up, and within a day the car
started to buck and shudder when I accelerated, and seemed like it
wanted to stall when I had the clutch depressed or had it in neutral.

I figured it may have been bad gas as the problems stopped when the
gas tank went to about a quarter tank.

This past weekend I filled the tank again. Within one day, the car
stalled on me six times within a 5 mile area. It stalled when I
stopped and was in neutral, and it also stalled when I would depress
the clutch to shift.

The car now stalls within three minutes at idle, in neutral.

Needless to say I can't drive the car.

The dealer now has the car and they said it stalled for them only once
at a stop light.

They told me they have no idea what the problem could be, but they are
researching it.

Anyone here have any ideas?

Note, that the temperature here has been in the 90's for the past few
days.

Thanks
