I think it may be the o2 senzor by bosch. The car wouldnt flutter before installing the new sensor.
Also just took it for a drive after sitting around all day and with a cold engine theres absolutely no flutter until she suddenly warms up and it kicks on the sensors im assuming...
Oddly this $200 sensor was also discontinued according to my parts store. So I called in and im going to defect it out. And friday I am getting a new denso for $10 more. Hope this is the fix... Can anyone weigh in on if an o2 sensor would cause this behavior?
