I have a 1997 2.4L sunfire and at random times when I'm idling at a stoplight or something the engine will just shut off. Now I've taken it to the shop eight times in the past month and they still haven't fixed it, first they told me it was a cracked circuit housing, then I got platinum spark plugs, and then they told me I needed a whole new water pump and thermostat. After getting all that fixed and paying over $1300 I am broke and out of ideas. I really think it is some kind of electrical problem because the car is not overheating or anything, oh and it's a convertible if that makes any difference. This is causing me to have a nervous breakdown so if any of you have experienced a similar problem or have any ideas, I'd appreciate it. Thanks.
