After I did the hose job I'm not getting any boost. She just hesitates and backfires under load. Today I noticed that everytime she hesitates, the check engine light comes on at the same time. So whatever is causing the check engine light must be what's also keeping me from getting boost. Any ideas?

 

dude, try what this attatchment tells you to do. Tells you how to get ecu codes and how to read them.
