The IAT and the IAC are no longer showing a fault code, but the O2 sensors still are. They were installed by Firestone in Livonia, MI. I will call them first thing tomorrow AM. When I drove it home from Midas this afternoon (They found nothing wrong with the exhaust.), it ran as if there was no problem. However, when my grandson ran the diagnostics, it was still showing the O2s. I will get back to you tomorrow AM after I talk to Firestone. Thanks.
No, I looked at the receipt hoping they would be there, but they were not.
Firestone in Livonia put Bosch O2 sensors (# XXXXX and #13937) in my Pacifica. I am in touch with their consumer affairs corporate office. I am asking for my money back, minus the engine diagnosis.
Thanks for your help.
