Q: My engine will start, but it idles rough and then stalls out.

asked by on

I got into an accident on the front end but didn't see any visible damage to the engine.

My car has 215000 miles.
My car has an automatic transmission.

Hi there. Getting into an accident, may have created a poor electrical connection in the engine management system. Starting the engine, having a rough idle and stalls could be any number of component failures. Identifying whether there is a loss of fuel or spark, would help to know the direction of repair.

A fuel pressure test and spark output test needs to be performed. To avoid any unnecessary repairs, I recommend your vehicle’s starting and stalling condition be diagnosed and repaired by a certified technician, such as one from YourMechanic.
