I recently did a b16 swap to my hatch. Car had high idle at cold start 3k but dropped to 1200 when warm. The car would bog at 5500 and vtec would not engage. started throwing a TPS code and a IAC code (7 & 14) adjusted the TPS and cleaned the IAC and they both went away. Took the car for a drive at 1/4 throttle the car will act like it engages vtec but it breaks up and bucks. full throttle the car wont go past 5500 just falls on its face. The car is my dd so i drive it to work and back only at this point. After about 10-15 miles it throws a Fuel supply system code (43) and the car will buck and have trouble holding speed generally 60mph since mostly highway driving i am using a ctr trans so im around 4k rpms. Today i replaced the TPS sensor, IAC and my fuel pump. and it still throws IAC (14) and fuel supply system (43) but now it cant hold a idle bounces between 2k and 3K and has trouble getting up to speed. not really sure what else i should try. the motor does have some head work done to it and im using a p28 ecu tuned on chrome that is tuned for my injectors. whats done to the motor is.

brian crower stage 2 vtec n/a cams
brian crower titanium valve springs and retainers
Rc 370 cc injectors
Blox intake manifold + 68mm throttle body
Aem fuel rail
dc sports 4-1 header
