Fracking Hell, I had a whole paragraph reply written when I hit submit the page failed to load and lost all the reply.
So here is the short version. O2 sensor code is normally due to the ground on the firewall side head on the drivers side has came off or gotten corroded. Check the ground wire on the side of the head, if it is good, then replace the O2 sensor. EGR Sensor is usually due to the EGR solenoid going bad. So replace it. ------------- Capt Fiero 88 Fiero GT 5spd V6 Eight Fifty Seven GT V8 5spd. |

Where is the ground located? Is it on the engine or the firewall. My O2
sensor has been spitting codes at me to, but I couldn't get the old one off to replace with the new one I have, so I gave up for a while. Thanks. |
