Thought i would post a new cold start vid, for about 6 months, i think i have noticed a smokey start 148K miles, been using valvoline 10w30 for years, i switched to Max life last oil change truck drives great, thers a slight idle issue when parked or in drive at a stop. Not shure no codes yet it might be the stock EGR playing with me, will see. Its kind up a miss but not that bad, Ty, can alabrate the issue.

can't find any vac leaks yet

Everything is up to date new plugs/wires/cap/rotor/coil,

Exhaust, you guys should know buy now but, hedman shortys,magnaflow y with cats,cherrybomb extreme.

 

I'm thinking that the slight puff of smoke at initial start up is oil from the valve guides. Its an intermittent thing with his truck and it doesn't always do it.
