Just curious, but why are you sure part of the problem isn't the O2 sensor? rach

Because when a cold FI engine is first started, it is in open loop mode and the inputs from the O2 sensors are ignored

Thanks TBone. As you know, I am not good with newfound FI or emissions technology . I'll look up how "open loop mode" works. (and stick to the old models) rach

Beside Tbones response, I would suspect that the o2 sensor is telling me that I'm pumping some unfired gas due to long cranking periods? bg

Why stick to the older models when the new ones work so much better.

While possible, it is also highly unlikely. By the time the system returns to closed loop more and is paying attention to the sensors that way, any excess fuel should have been burned away and if not, you would be smelling a fairly strong smell of gas. The sensor may either be bad or is indicating an actual fuel delivery problem.

Dear TBone,
because I have no clue with the new ones, and TBone, maybe I'm an old dog afraid to try new tricks! (pun intended!) and no money rach
(not that if I had the cash I wouldn't buy a top-of-the line charger srt8 toy, and then go to town putting a Cummins 610 diesel into this summer's ram project
