last night i had some other turbo civic messing with me so a floored it and after i let off the gas my car started acting like it was going to die. The car would only act like it would die uner 3500 rpms and above that it would do fine. It was backfiring and dieing even if i had it floored. So i pulled over and changed the wastegate port from the bottom to the top and the car ran fine until i get on it again and i does the same ****.

 

um... if you have a tial.. put the line back on the bottom.

also, we need more info. like your setup and such

also, do a compression and a leakdown test
