ok, im not going to get too technical with mods and such on this one just yet, i just need some second opinions. my car started just recently created excessive whitish smoke out of the exhaust, but the amount of smoke can vary under my control, but ill get into that later. it smells exactly like unburned fuel, basically like an outboard motor, and the engine has a kindof a "stutter" at lower rpms and somewhat noticable in the uppers. i have a few ideas and know a few things of what could be causing it, and i am working on those aspects, but any technical advice or just plain common knowledge would be greatly appreciated. my car is highly modded, but im not going to go into that yet unless someone wants to get into it.

b.t.w. my car is 1990 Turbo II

 

That sounds exactly like mine when I blew an apex seal

If you have just instaled the Autronic and have it set in 2 stroke mode or something smoke like that then you will have this exact same problem, the car will start but SOOO much fuel will be going through it that she will do this.

Please send me a copy of your .cal file that is currently in your ecu with your list of mods (full list) and I will look at it for you
