I just had the MM, TBE, and CAI installed Friday. I also filled up and added some Lucas fuel additive (32 oz. Prob too much). On Sat. afternoon, after putting 150 miles on that tank, I started the truck and it ran very rough @ idle then rougher when I put it in gear. Unplugged MM and rough idle went away but timing was off. Plugged back in and was rough again. Turned engine off, and back on, and no rough idle. Drove good just rough at start up and idle, sometimes. Then I tried starting it this afternoon and it took 6 times to start, blew white smoke, and was very rough. Drove it to see if the problem persisted and it went away after the truck warmed up. I'm stumped guys. Anyone know what this problem could be related to? Too much additive or Mileage Max bad???
