I had one guy tell me it was a fuel thing, because my car runs a little lean below 3300 rpm, a/f is at like 16 below 3300 and just a hair over 14 from 3400 to 5600rpm. I bumped up the fuel pressure and it still bucks at really low rpm like yours, usually on decel but also if I'm trying to coast in gear. Another friend told me it's the cam. I'm running the TFS Stage 1 and he said i might need a chip to smooth it out. I'd already checked my tps and it was set at like .985 so I think that was fine.

I don't know either way so I've decided to do my level best to keep the rpms up so i don't have that problem.
