Intermittent White Smoke/Loss of Power
Hi gang. I'm trying to track down a gremlin in my 05 F250. Twice in the past 2 weeks I have had a strange symptom. I left the truck idling at my friends house for about 5 minutes or so. After leaving their house, I got on the pedal aggressively (not down to the floor). After about a mile, I slowed to turn a corner. After turning the corner and pressing the accelerator, there was very little power (almost like it was bogging down, and wouldn't go above 1000 rpm), and white smoke was coming from the exhaust. I hopped out and smelled the exhaust, but I couldn't tell if it smelled like coolant or not. After a minute of letting it idle, I pressed the accelerator, and the truck went like normal.
I've been reading on here for a long time trying to figure out what this could be. Most people point to EGR cooler leak, but the truck doesn't seem to be losing any coolant. Could an small amount of coolant cause this? I also pulled my EGR valve to clean it, and it didn't seem to smell like coolant, although it was coked up pretty good. The EGR valve wasn't wet, but the deposits weren't dry like dust. Also, the turbo boost never goes above about 17-18 psi during heavy acceleration.
Any thoughts on what could be going wrong? Anything I can check to help narrow down the issue further?
