I recently bought it a few month ago with this code and it was misfiring bad I fixed the misfire hasn’t done it since the first drive. But she is still very sluggish with the p0016 code. There’s 0 engine noise also the cat was punched out when I bought it . The oil is kinda sludgy gonna change it again tomorrow but the motor sounds too good to be hurt, I pulled the cpas out already it looks to be replaced and or brand new and very clean I’ve tried everything. Also when it’s cold on startup it has a little power but once she warms up she’s a slug.
