diagnosing sticking injectors
Well, my truck starts terribly. It needs to idle for about 5 minutes before it will even move under its own power. It shakes, blows black smoke, and occasionally stalls shortly after starting. Once it's up to temperature, it runs like a top. FICM voltage is rock solid at 48.5-49 (keoe, cranking, koeo). When it first starts if you read the DTC's you get cylinder 2 contribution/balance fault, and cylinder 4 contribution/balance fault. I'm going to replace those 2, as I'm sure they're the worst of the bunch. Is there any other way of diagnosing the exact cylinders? Those are the only 2 that fail the contribution test, but with the way it's running, it sure seems like more than 2 are experiencing stiction. After I replace those 2 I'm going to switch to t6/rev-x, and re-test.
