15psi bucking/hesitation

[90AWDEclipse]

Ok so I get in my car one day and I get on the highway and, im at the top of my third and it starts to buck but it feels like it's missing. As soon as this happens I think back to when I previously fixed one of my spark plug wires that came apart, and I think thats the problem. So when I get to my friends house I pull it off and it comes apart again this time I fix it so it wont come off. I drive around alittle and it feels good then I do another 3rd gear pull and it does the same thing. I change the wire but it still continues to do it. So today I decide to turn my boost down to stock and see if it still happens, and it doesnt. So now im thinking something with the fuel. Im on the stock fuel pump and injectors but I dont know why it would just start doing it now. Iv'e been running 15psi for at least a month, please help me out.

Do a boost leak test.

Sounds like a spark plug issue. If your a member of tuners, your probably familar with gettin the NGK plugs. You mentioned fixing the wire. I would say get some new wires and plugs. Plus are sure and make sure they are gapped correctly.

The gaps might be off causing your to miss up top.

Also, try gapping the plugs closer to .025. This can eliminate problems missing up top
