I just got a vibrant intake tube and filter. Problem is when i installed it the car stumbed, and ran bad. Thought it was because I disconnected the battery. So I ran it and it backfired under the hood and the check engine light came on
. It only ran good when it was in the high rpm range. Went straight home and checked for leaks. none..
I replaced it back to the hot box. Ran fine. Switched back to CAI and ran bad again. Does anyone know what's going on.
