I also noticed that - I bet Ray was talking about EZK ECU, not APC.
Ray, I wager two Jacksons that it should be a darn easy fix. It had been fine for a long time and then it suddenly went wrong - it's a darn wire that was broken somewhere.
Let's check it once again. ENGINE NEEDS GAS AND AIR PUT INSIDE AND A SPARK SUPPLIED AT THE RIGHT TIME TO RUN. Period.
1. You checked the fuel system. To my humble opinion it was a quick and nice check. Let's assume you've got good gas in your tank and working fuel pump as well as fuel filter. Question - is fuel ECU trying to spray the right volume of fuel and do fuel injectors hamper it?
1.1 - you need DC meter to measure average voltage across injectors' terminals (say when idling) and another good guy having done the same on a running (I mean being in a undoubtedly good shape) car with NA engine. Better the same year (different ECUs, different AMMs - I'm not good enough at Bosch EFI to say whether any NA B202i sample car will work for you). Sorry but I've got turbo + Lucas EFI.
If both of you got the same values - your fuel ECU is ok. AMM is ok as well.
1.2 - check injectors. Four cans, clock able to measure 30 secs and a piece of wire in your fuse box will work fine.
Half a liter (not sure but Justin will definitely correct me if I'm wrong) in 30 secs? Good.
2+3 Air and compression
Man, if you had a darn fat mouse caught inside the air hoses and preventing the air to run inside your B202i - or if your rings and pistons got so worn that you're not able to reach 2K on idle - man, you would post tons of posts here on cold start issues long ago. So you issue is not about lack of air intake or bad compression.
4 Ignition
Yep, you checked your plugs and they're fine. But are you sure that the A/F mixture is ignited at the right time? I'm not.
I'm recalling a similar issue (the only difference is that in my case I had 2.5K RPM limit) with my 1st car. I tried to see "how stuff works" and disassembled my dizzy. And assembled it back... but in such way that RPM advance didn't work.
4.1 Check RPM sensor (behind crankshaft pulley) and its wiring.
4.2 Check the wire from fuel ECU that is sending Load Signal to Ign ECU (Tq signal in most manuals). Man, I wish I knew which #...
4.3 Have a look inside your dizzy. No, don't break it into pieces but just take off the cap and check what's inside.
I bet that it's either ignition or smth VERY-VERY strange. So once you're not me them you don't attract strange issues (like a know in the suspension cause by a small stone happened INSIDE your tire) - that's ignition.
Yours,
