just looking for a little help from anybody who could help me figure out the idle issues my car is having. seems that the AEM cant control the idle of the car since the unit isn't made for the IS300. so one tuner added a lot of fuel to compensate. but then I'm running super rich all the time. i took it to another shop and they leaned it out but now the car stalls all the time. like when I'm sitting at a stop sign or red light the car will just lean out and stall. very frustrating but sounds like there's no happy medium. anybody having similar issues? any input?
