Hi Nick,

I have a 92 325 nv with 100k miles on it. When the revs are below 2000 rpm and I get back on throttle the car bogs and missfires. Sometimes ill hear crackling from the cat conv. This winter I have replaced plugs and a bad coilpack as well as the vc gasket. I've narrowed it down to : O2 sensor, coil pack, bad cat, dirty maf or vacuum leak in ccv. What are your thoughts? Thanks

Only a few things can cause a misifre, you'll need to see what is missing. I would check spark, fuel and compression on all cylinders.
