I just got a 1997 civic w/ b16a2 swap. The guy tells me it needs p72 ecu to run, bc the p2t ecu (original si ecu?) will not work. The car is retarded slow, gets absolutely no power from 1st to 3rd gear. I have to shift @ ~4K rpm IN EVERY GEAR, which kills mpg ratio. Autozone says that I need a new distributor, spark plugs, o2 sensor and wire set. Should I believe autozone and hand over the money, or believe the guy who sold it to me, who says he's never changed the distributor?
