white smoke problem just got worse...now whenever i get on it, as soon as i let off it puffs some white smoke out for a second or two

it also does this but for longer in the morning in 40*ish weather ... tested the glowplug relay .. tested 12.3

what else can i look for and how do the wiring harnesses on the valve covers come out to check the glow plugs?

thanks
nic

 

nobody has any ideas? i could use the help. . .

 

White smoke in the morning, 40ish, no worries, but as far as whit smoke after WOT, somehwere in this forum I have read white smoke is something like 40% un burnt fuel... But as far as white smoke and my experiences, have someone hit the gas and smell for a sweet smell. Check your coolant level. IF you see no problems there, un install your hypertech, you may be over fuelling for some reason.
