I have A 2008 z...broke down on me on Monday....when i started it, it had a rough idle...had bad misfires and finally wouldn’t start...ran the codes and it had two 02 sensor codes and a misfire code...pulled the plugs and the plugs were fouled....the car runs rich after installing test pipes....i replaced the plugs and tried to start it...it cranks but doesn’t turn over...when you spray starting fluid into the intake it’ll turn over but runs really rough....it has a new fuel filter...new plugs...new intake filters...new coil packs....I’ve cleaned the MAFS.....any ideas on what to possibly check next would be great...the mounts for the test pipes are a few inches long where the 02 sensors mount which has made it run really rich...should i swap those test pipes and install new sensors?

both...this happened once before about 2 months ago...did a few things to it and it ran great...got in it to go home from work and it completely died...replaced the plugs and it just cranks...**** some starting fluid in it and it would turn over but runs horribly
