The Windsor is chewing the fuel again
Replaced the 02s 2000ks ago when it had the same problem That seemed to 95% cure it Now a couple of years later its back to running rich and hunting at idle again As soon as it switches to closed loop the fuel trim heads skyward, in open on a cold start they start at 18% then fall to 3% till the ecu switches to closed. The first vid shows how the trims react on a warm start up ,on cold start they drop to 3% Can someone who knows this system have a look at the two YouTube vids and give me an opinion, Thanks Bret. https://youtu.be/32EKs5Tnen0 https://youtu.be/JaYz8f5UuNQ Also disregard the Forscan vids on YouTube, that was from last time (4yrs ago) Last edited by Caprobbo; 14-06-2019 at 08:55 PM. Reason: add more info |

Your second video shows one of the O2 sensors switching even when the engine is off. It should go full lean at key off. What brand of sensor are used in the videos.
