Another problem to really throw you off is that when the engine is cold it runs very uneven: sounds like one cylinder is having problems but I can't for the life of me figure out which one. And yet the plugs are identical. I have unplugged injecters one at a time many times but I can't quite get it with just my ears. It happens at all RPM's while cold. My neighbor is a big VW nut and mechanic and I have him stumped as well, even after he listened to it himself. This unevenness makes it a pain to drive before it is warmed up, then it is smooth as silk. It is also smooth for about 2 seconds immidiately after starting, which would point to... mixture? injectors? While meticulously checking the FI harness (recorded all ohms) I discovered that injector wires 2 & 3 were switched, correcting this made no difference. I also inspected the FI points, they looked fine, fired right on time, and both dwelled the same.(160 and 165 deg about, with a protractor) don't laugh, I'm desperate Sorry to be so long, please help.
