Hi all,

Ive got a catless, true dual AMC 304 V8 with a fuel only 1127747 TBI setup inside a cj5. It is working very well, but now that I have the top off for summer, I can smell the exhaust some. It smells fine in most cases, but during DFCO, the exhaust wreaks! Like eye wateringly bad. I know it's going lean, because I can feel DFCO kick in and slow the rig down, and my laptop shows the O2 reading very low voltage.

So why is this happening? Is this a common thing, or is it because I'm running fuel only?

thanks,
