So as ya'll know, since I've finished my swap i've been having problems with the motor bogging at 5500rpm in every gear right when vtec should kick in. The codes i've thrown since the swap, were, random misfires, all 4 cylinders misfires, and use to be randomly a knock sensor code now permanent knock sensor code. What I've done in the past 3 months. New Ngk performance wires, new cap and rotor, new/bigger injectors 440cc, new fuel pump 255lph, aem fpr, new main relay, swapped out tps, timing has been checked and still the problem remains Also put in new NGK iridiums this past Saturday after only having my other iridiums in for 3 months but figured since I changd the wires might as well change the plugs. The only thing left for me to do is change the fuel filter and knock sensor, as on Monday while I was going through the engine I noticed that the knock sensor wasn't were it should be, the clip was just hanging under the im. Other than what's listed I don't know what the problem is. Here's what I'm running, just in case you don't remember: 2000 Civic Si, with built 2000 Integra Type R engine Head is ported and polished, Crower rods, JE pistons, 12:1 compression, Skunk 2 stage 2 cams, REV Valves springs and retainers, skunk 2 intake manifold, Act flywheel, RPS six puck sprung hub clutch, AEM cam gears, AEM fuel rail, STR cam seal, K2 cold air intake, throttle body spacer, JDM ITR 4-1 headers, APC catback exhaust system.
