I have a KL-ZE curved neck inside my 1997 MX-3. It was a B6D (107 HP). Now it is a KL-ZE curved neck with K8 PreFL cable harness and KL31-ECU and K8-PreFL-VAF.
It runs great.
But I have three questions:
1. I get an error "15": O2-sensor left. That means front exhaust manifold. Is it a real error or is it reasoned of my KL31-ECU und K8-PreFL-VAF?
2. When I'll run the engine in diagnostic mode (bridge GND & TEN), the engine starts, but it goes out (stall) immediately. I can "give some gas", then the engine runs and when I take off the gas very very slowly, the engine falls into idle with luck. What could be the reason for it? Could it be a wrong ignition point, the O2-sensor-error, or a wrong idle speed?
But in normal mode (without bridge), the engine runs perfekt. The idle is about 700-750 rpm, very constant. I have no problems. Though I'll check the ignition point to be on the safe side, but I can't get it into a stable idle in diagnostic mode?
3. I have installed the 16V-fuel pump (B6D 107 HP). Is it a problem? Should I swap the fuel pump to a V6-fuel pump?
Could you help me?
THX!
