EM1 Bogging out

[project_EM1]

ok my em1 is bogging out when i drive i had a bat cat. converter but it has since been replaced.
so its not throwing the P0420 code any more, but its still bogging, and my question is.
will riding on a bat cat for a long period of time be bad for the egr and will a bad egr make the car bog also.

it may have caused some other things to clog up such as iacv screen and egr valve could be stuck as well.

well if the iacv is screwed wouldnt it have a jumping idle

mine used to bog down when you hit the gas, is that the problem. going 55mph, hit the gas and it bogs/delays for a second. send me a pm and let me know i may be able to help you on this one.
