low throttle problem

[toyotwo91]

Today I changed my bov cause I thought it was leaking. I went back to my stock one. Now all the sudden my car runs bad. At high boost it runs fine. But when cursing w the the throttle barely cracked it sorta chugs along. Only way to explain it. Maybe alil like a miss.,also its missing at 4500 rpm. I read through the search, and seen the 4500 cut out is from a boost leak. Why is this? I'm currently looking for a leak in the stock pipe but not finding anything

Did you do a boost leak test?

You can't be to sure until you actually do a blt. Sounds like you got a major leak somewhere. Recheck the bov and especially the bov line(s)

Don't forget to check the brake booster vacuum line. Also you might want to look into rebuilding the throttle body if its leaking.
