well, I just got done installing my MSD digital SCI, new plugs, new air filter, oil change, new radiator, coolant, hoses, everything. I started it, drove to work, running better than it ever has. drove back, same thing. started it to drive to my mechanic to put in my clutch & flywheel, and it runs HORRIBLY! the exhaust sounds like a BLUB-BLUB-BLUB-BLUB. the motor shakes horribly inside the engine bay, too. I did do this before I installed the new stuff, but it usually kicked itself out of it pretty quick. this time, ti's not going away. since the problem today, i have: inspected the o2 sensor & wiring, set both cam gears to 0, replaced the rotor, replaced the ECU, checked the plug wire ohmage, ran a compression test ( 173, 150, 160, 167). I tried driving it in it's horrible state, and one time when shifting into second, it kicked into regular running, then immediately back into the crap. When I look at my a/f ratio gauge, it says i'm running really stoich upon startup (which on a honda is pretty rich) Then it slowly goes back into the lean led area, but still runs like shit. any suggestions? fuel pump? filter? sensor? actuator? valve? no idea!!
