backfiring?

[mk3supra]

my car seems to backfire when i let of the gas for a second and push back on the gas. It is a loud poping noise. It usually does it in 4th gear any idea what this is or why its doing it?

if you have a bov venting to the atmo its semi normal. mine recently started backfiring more because of a fluky knock sensor.

any codes? check your ic pipes also for leaks

i have an aftermarket bosch bov hooked up like the stocker. No codes. I need to check for leaks.

I would recheck the all of the clamps because some can become loose and check the 2 clamps by the Throttle body.

is there any other reasons why this might be happening other than a boost leak?
