Need help troubleshooting
Okay guys, I bought an early 99 F250 about a month ago. The guy who had it before me was terrible at maintenance and I've been working on getting it revived.
Here's what been done:
by the dealership: changed an injector and a couple of sensors (not sure which) they also did a test no the turbo and it checked out ok.
by me: changed oil, flushed coolant, changed fuel filter, diy intake, 4" straight exhaust, working on getting the steering and suspension fixed.
Issue: two nights ago I started up my truck after it sat for about 15 minutes and it did this weird loping thing pretty harshly. I turned it off, and started it back up about 5 minutes later and it fired up correctly. Now I'm noticing when I start it that it has a whitish smoke coming out of the exhaust and I can't figure out what it is.
Any clues on what I can start looking at?
