Hi guys, I am a noob here but not to Hondas one bit. I just bought a DA with a a B16A, new tranny and clutch + cable. The Body needs minor work and re-paint. But overall it was a great deal. Anyways, I believe the motor has a GSR Intake manifold due to the fact that it looks like a blimp compared to the B16 manifolds I have seen before (Only pointing this out because of Code 3). The car is throwing two codes at me, Code 21 and Code 3, both seem relatively simple, but I would like a second opinion as well as some info on the vtec solienoid ground. I have done MPFI swaps and single cam swaps so I know whats up, but I haven't dealt with vtec or DOHC. Anyways, any help would be greatly appreciated. Thanks. Oh and the ECU is a PR3 OBD0. P.S. Diagrams or pictures would help a lot.
