P0278 trouble code help

Was driving today just cruising around 65 when my truck hiccuped and immediately started to mis, vibrate, & white smoke terribly. At idle it has a bad miss & lost lots of power when driving, is it a injector issue, cracked piston, or valve train issue??? anyone with info please post...

truck is fairly modded with spartan & elite parts, if this matters....

White smoke smell like diesel? Sounds like a injector to me.

Yeah I'd say for sure, might wanna get that taken care of before you run it much more.

Re: P0278 trouble code help

if its hung open you will wash the cylinder very quick and will need a new motor.

Re: P0278 trouble code help

Thats not good, if cash is a issue you can think of boring that hole out and resleving it and thowing a new piston in and go.
