My 2000 accord idles low at times and before I can put it in gear my car will shut off. I bought some sea foam motor treatment. Has anyone had this probably or know how to resolve this issue? Sometimes it will fluctuate between 500-800 and then shut off. Any help is appreciated. Thank you

 

Welcome in,I would first start with a good throttle body cleaning,and then check IAC valve and clean it,it maybe as simple as that.
