Lsvtec problem

[monkk]

Got a B18a1 bottom end with b16a head swap in my civic EF. Car sputters from 0-4000RPM but then after 4000rpm it picks up power and goes normal. Car is throwing code 7 right now cause I just replaced the tps sensor and guessing it needs to be set at the right voltage but I don't see why that would cause the problem. Anyone have any suggestion?

Yes that will cause an issue, the ECU uses the voltage from the TPS and turns that into fuel output which could cause your issue, adjust the TPS properly (run a search i've done a write-up on it) and see how it goes.
