My car is running really rough and has a loss in power. I replaced the plugs and plug wires and pulled and cleaned the fuel injectors and it is still doing it and getting worse. Not sure where else to start. 1995 Chevy cocisa with 84000 miles on it.

Check for spark to the plugs with engine running. Perform a compression test to be sure the motor is good

I ended up pulling the plugs on cylinders 1 & 2. Attached picture is what I found. Dropped a new plug in spot 1 and got most of the power back. It's still idling rough and is sucking or pushing air around the EGR vacuum harness. Can't seem to locate a replacement part for it anywhere.
