After the car warms up, the engine light comes on and the engine begins to sputter and cut out and will stall if the RPMs fall below 1500 or so. When it does stall, the engine will struggle to start back up again but it will, and continue to sputter on. Any advice is greatly appreciated. Thank you.

Answers from the Automotive Experts

Amanda J. Pierce, MBA Mark, I recommend checking your Idle Air Control Valve (IAC). At times, this can be removed, and the head can be cleaned from carbon build up. If this improves your drivability, then replace the IAC valve. Also, make sure that your spark plugs and wires are in great working condition. Lastly, you can typically visit your local auto parts store, and they can read the code setting your check engine light for free, to help you further hone on your issue. Hope this Helps!

Kristin Brocoff, Director of Corporate Communications at Mark, without knowing the diagnostic trouble code(s) or pending code(s) stored in your car's computer, we can only take a guess at the problem. However, it's important to know that it's never a good idea to ignore a check engine light, even if it's intermittent. A small problem now could eventually snowball into a costly repair. I checked with the ASE-certified team of techs here at Corporation. Again, they'd need more data to accurately diagnose your vehicle, but your description of symptoms seem to incdicate it may be a cam or crank position sensor failure. These sensors are commonly known to "act up" when the engine is warm. It's also the most common repair on a 2000 Dodge Intrepid, according to the CarMD Vehicle Health Index. You can lookup your car at for free. We encourage you to have your car looked at by a mechanic you trust or to use an OBD2 code reader or product such as the CarMD Vehicle Health System to diagnose the problem and get it repaired so you can get back on the road without the stalls and sputtering. Safe driving! Kristin Brocoff Corp.
