i have a 94 Z28 LT1. I need to know how many O2 sensors should be on this car and how many wires are running to the sensor... I just got the car together and got it to crank but it was running ruff.. Now the starter locked up so i had to order a new one today... Any tips on the O2 setup and advice... Will the O2 cause it to run rough? Thanks

 

You should have two pre-cat O2s. Each has four wires running to it. Bad O2s could cause fueling issues and poor running.

 

ok thanks for the info.. right now i have no sensor connected so i need to find another one

 

Use Shoebox's harness photo to track it down:
