help..after storage:idle hunts,Super Rich AFR`s
l have a 1984 3.2 Carrera that l laid up over the winter. l just replaced the battery and fueled it and l now have super rich condition (19.0+ AFR`s) ,the idle hunts and of course black smoke from the rich running. Before l dive in l figured l should post. l have lots of guages and fuel pressure is about 30 at idle (l can adjust this) and as l said the PLX wideband shows 19.0+ AFR`s. This PLX also sends a narrowband signal to the ECU.....so l`m thinking it`s possible the WB sensor is faulty and causing the trouble? anyone?
any help appreciated

Isn't 19.0 AFR "super-lean"?, not super-rich?
19 airs for every 1 fuel = too much air.

.......good point, you are correct sir. The sensor shows lean but running condition is pig rich.l will have to re-install a narrowband sensor and jump the signal to the ecu,bypassing the PLX..l appreciate the response,gets me thinking
