Hey guys, just got back from a trip to MD from NC. While up there I had the truck fired up on one of the days with high idle mod on to keep the AC going strong, and so the kiddo could watch cartoons on the AppRadio I installed a few weeks back. I walked into the shop for a few minutes and came back out to check on the kiddo. I seen white, white blue smoke coming out of the exhaust. I freaked ran over shut it off. Didn't know what to think. Fired it back up, it still smoked a bit but not as bad. Took off back to the house, and was able to get it to smoke again from take offs, and power braking it to load the engine. I don't remember FICM voltage at the time. On the trip home I kept the scan gauge locked on the FICM and it bounced from 47.5 to 48 volts, never over 48 or under 47.5. But I noticed at cruising speed of 70mph that the front of the truck would shake and then smooth out of decelerating. Also at lower speeds on decelerating it would almost sounds like an injector nailing. I assume I have an injector mis firing. Everyone I have seen have issues says check the FICM first. SO I get home from work today, turn the scan gauge on, put the FICM main power on, and start the truck, 48,
47.5, 45.5, 44.5, 44, 43.5,
and lowest at 43 even. So from what I have read, looks like I need to get ahold of FICMrepair.com to get it fixed. Whats yall's opinion on the matter? I figure i am trying for economy in mind and looking to get that tune as well.
