I have a 93 es300 and car runs perfect but idles low and looks to cut off when in park and sometimes when in drive at a stop light, any ideas on what may cause this guys. Getting frustrating at this point. Thanx in advance for your help.

 

Clean your Idle control valve, throttle body and change your pcv valve and air filter. Don't forget to check for any vacuum leaks in your intake. If this doesn't fix it then report back. Good luck!
