Please help. my 94 is having idle and power loss problems. Drove to work today with no problems besides my slightly lopey idle (minor vacuum leak I think) after work started her up... idle was rougher than usual shaking the whole car. and the exhaust note had a weird hollow sound to it with the smell of gas in the exhaust. When I drive the car there is no power when I'm accelerating like I'm driving a V6. made it home with no CE light coming on. ran my codes got a code 33 with engine off then the same code 33 again with engine running (bad EGR I think?). But the real kicker is when I ran the Cylinder balance test it told me the #4 cylinder is dead. I changed distributor, plug wires, ignition module and all plugs within the last 2 months and she was running fine so I don't think it's wiring. I am stuck and any advice would help.
