ok. here is the problem. got a 93 sentra. originally with 1.6 now i got a det in there. When i try to start it in the morning it takes a couple of tries. Once it turns over I have to keep giving gas to bring it up. I also have to hold it steady 'till it warms up. If i try to drive it it bogs, misfires, jumps, bounces, break-dances and jitterbugs. A/f guage seems like it runs lean, but wait theres more. Once it warms up it drives fine. A/f guage is fair, sometimes a little rich but no biggie. And when warm it wont idle right (1200-2000). But it will have a ton of power. If i let it sit (2 or more hours) it will give me a hard time to start it up. Any body with an idea please reply. I usually would just try to fix it myself but this s**t got my blood pressure rising.
