2008 Yaris bad idle and stalling - Toyota Yaris Forums

Okay so I am having an issue that has been getting worse over the past few months. At idle the RPMS drop enough to violently shake the car then RPMS jump back up or the engine will stall, the shake happens most of the time the stall maybe 2-3 times a day. There are no codes,alternator reads 13.8ish at idle and 14.04ish at 1500RPMs I have cleaned the throttle body and MAF I have 24inhg vacuum at idle I checked for leaks none found.
Any help would be appreciated as my scan tool at work does not read new Toyota's. I can only check for codes and see the freeze frame data at the time the code was set but as I have no codes I am stuck.
