What do you think?

Its finally running but it just didn't drive right. Finish up a installing h/c/i and a mass air conversion on my car, but when i took it for a drive it was missing. At first I thought maybe one of the wires in the conversion was not connected good enough, but the car will idle just fine. I set the timing to 14 degrees, have new plug wires, and have new plugs gapped at .40. Do you think the gap is to small. Also my fpr gauge was at 38psi with the vacuum on. Also since my upper intake only has three connections for vacuum lines (1 going to the vacuum tree, 1 to pcv) I ran a t-fitting for the fpr and the egr vacuum line to the upper since I wanted to keep the egr still. What do you guys think I should try?

Vacuum leak, timing issues, bad plug(s), bad plug wire(s) are just a few possibilities. Does it miss when you are driving at a steady speed or wide open throttle or both? Did you set the timing with the spout connector removed? What kind of mass air conversion is it?

Yeah it has new plugs and wires. The mass air conversion I pieced together, with a a93 computer, stock meter, and a coversion harness I bought online. I didn't try to get on it cuz it didn't feel right when I was driving it. I am going to try to check for vacuum leaks and seem if maybe turning the mass air meter will help. Yeah I will try to take some timing out too.
