Conversation Between Hatch Man(GsR) and SYCKDC23

hey whats up... someone told me to message u about problems im having with my car

Went to advanced and ran the obd2 scan on the car and heres the codes that were thrown.

P0170 fuel trim malfuntion.
P1337 ignition system or misfire
P0172 System too rich

Any ideas what these mean, and where to start to fix them?

Motor is rebuilt with only 750 miles on it now. used all the same sensors and stuff from my old motor, just used the new head and block.. Car will sometimes idle fine, but other times it will idle to zero and cut off. Vtec doesnt sound right at all when it hits... its like it hits then just dies down, if u were to hear it you could tell it just isnt right.... but any help would be appreciated.
