so thats the proper way to adjust the idle? I thought I would have to go in through the computer and stuff. I'm going to put on my fuel filter, check the EGR valve, the throttle valve blades, and the throttle positioning sensor first to see if that helps anything. If not then I will try your way.

 

Well I went outside to work on my car today and trysome of the things you guys suggested. I want to check the EGR valve but I can't get my hand, a wrench, or a ratchet back there to take it off. Its so frustrating not being able to get to anything on these cars. Anyway, I was looking around and noticed this hose dangling under the car not connected to anything. I traced it and it runs down along side the intake into the vacuum control solenoid. The picture with the colored rings is not of my car but the device circled in green is the vacuum control solenoidand thats what the unconnected hose is going to. Now if I could only figure out where the other end of the hose goes. Herearesome pictures.

 

I'm having the same trouble on my 95 almost too a perfect description...Its annoying as hell! Keep us informed!

 

i tried watching that video but it says i have to log it to your album.

 

I also have a 93 z28 but after buying MSD distributor, electric water pump, fatory fuel pump, hypertech chip, MSD coil, wires, plugs, ect it will not even start now. ran fine for the last year with a few idle surges untill one day it went bang and than nothing.......
