Question Answered: Why does my 2000 Elantra shut off completely when I slow down or coast?
February 10, 2012, 07:12 PM
I'm not a trained mechanic, and never pretended to be. My only advice would be to start with the "cheap" stuff. I had a similar problem on my Elantra, and changing the plugs and wires fixed the problem. I also found that there was a disconnect with a hose from the air filter to the motor. Check all air hoses and tighten everything down. Hope this helps.

If the problem is severe enough engine performance will suffer and the Check Engine light will flash on and off.</p>
