Help with electrical or fuel troubles?
My 94' Z is idling rough after the car warms up. The engine is vibrating pretty bad. There is also studdering or hesitation when I am coming to a stop or rolling of the line slowly. There seems to be a power loss at light throttle, open throttle is okay. I can also smell gas. I have a new opti, plugs and wires. I think I might need a new fuel pump? What does everybody else think?

Prolly right. If it's not throwing any codes, check the fuel pressure. Here's a good write-up on shoebox's website. It tells pretty much how to troubleshoot the entire fuel system. http://www.shbox.com/1/4th_gen_tech2...essure_testing
