On startup in the morning (plugged in) 20° or so I get a good amount of smoke (blueish) I have a AIC and once it warms up a bit it goes away, but the exhaust has a strong smell all the time (like a reddy heater running out of fuel). It starts good and seems to run good. Every once in a while it will flutter (like a skip) when going 45 and in OD and trying to speed up. If it shifts down it goes away. Other than that it has good power most all the time. Stock with Superchips tuner, K&N filter, open exhaust all the way, brand new GP's & GP regulator, uses no oil, 211,000 miles.

What do you guys think?

 

injector orings maybe worn a little. try letting the gps warm up for about 30 seconds or so before cranking it over.

 

Any other views?
