Code 45 after cold air install

[Stone]

I replaced my cone are filter with a cold air intake kit and now im getting a code 45. It took a few days before the code showed up,but it seems to much of a coincidence . I replace the o2 sensor but still got the code. I did this at the start of last winter, but I think the kit came with a new EMC.

Thanks

I would suspect the MAF in this case since you had to disconnect it when doing the cold air install... What are your readings from the Scanmaster?

iac -35
af- 05
l8 - 38
int-128
ats-72
tps-38
bl-128

You might have a leak between the MAF and the throttle body.
