I’ve been noticing white blueish smoke coming from my exhaust during my driving. It usually lasts about 5-7sec. It started to happen about 3-4months ago and recently had a check engine light come on ( spn:5319 fmi:31 ) I had the 7th injector cleaned and the issue went away until now. Is the 7th injector overspraying and causing this to happen? I was thinking of installing a new injector and hoping it solves the issue. What would be the likely cause of this issue?
