E46 1999 328i MDK throttle body issues

Fchassies · 08-31-2024, 01:41 PM

I recently purchased a 99’ 328i and the vehicle has a cel and a whistle on acceleration below 20% throttle. I inspected the intake boot and it was very bad so I replaced the upper intake boot. No luck, so I took out the lower boot inspected it and was going to swap out the throttle body but the new one doesn’t fit. Cars back together and the issue is still present anyone have any ideas what could be causing this?
