[QUOTE="6speedsd, post: 1433879, member: 1242"] On an 03... My old man was driving it the other day, said it started to miss. About like it dropped an injector. Said before he got it home, it was so bad it would barely pull up the driveway. I put AE on it Sunday, and it showed injector contributions for 5 and 7. It fired right up, missing on one cylinder. Did power balance, and although it wasn't a straight line, it wasn't dipping or spiking badly. Started shutting down injectors one at a time...started with 7, no change which confirmed it wasn't firing. Went to 5, no change. Then all of a sudden, the longer it ran, the worse it got to where finally it wouldn't even idle. I could Rev it a little and keep it running long enough to shut down all 4 individually on the passengers side with no change (all the evens you could tell made a difference when disabled). Tore it apart today thinking bad harness. Every wire from the injector connector to the harness connector ohmed at like .3. Put it back on and in the process of taking the FICM off my truck to put on there and see how it acts. Voltage test at the pin on his showed 48v plus the whole process. Trying to rule out a bad logic side, as he had bad batteries a month or so ago. Just doesn't seem feasible that all 4 odd injectors would crap out once. When checking FICM voltage it fired right off, still sounding like a miss on one. So whatever is happening, as it runs and warms up is when injectors start dropping off. Anything I'm missing here? Will report back after trying my FICM. Sent from my SAMSUNG-SM-G900A using Tapatalk [/QUOTE]
