Was unable to replace coils due to national back order.
I was averaging 14mpg on the dash and it jumped to 20mpg.
Car also felt smoother.
I mostly track my car so mpg is not my concern but, as mentioned here it's a good indicator of something needing attention.
mostly noticed the improvements driving to and from track, plus city miles. So a lot of freeway miles. |
Thanks. This is great info.
How much did the injector refresh cost you? Did you have to send yours in? What was the turnaround time?
Were you getting any CEL codes when you replaced the O2 sensors? |
The injector service came out to $181 with expedited shipping. Yes. I removed my oem ones and sent it to them and a week later was back.
No CEL before or after O2 replacement. O2 sensor are very delicate with the wire side. I did not twist any wire installing them and did not add any additional anit-seize or lube to any threads on the O2, it was installed the way bosch sent. There is already a small amount on the thread added by bosch.
