99 4.0 OHV miss
In the process of replacing my timing cover and gasket I also noticed that I had a small leak on the lower manifold gasket so I removed the lower manifold and replaced with a new gasket. When I started it up I noticed that I had a slight miss. When I took it apart it was running fine just the water leak and I now noticed that I get a sulfur or gunpowder smell that I didn't have before and when I hold the rpm's at 3000 for a while it will climb up to 4000-4500 rpm's and then back down. No codes have been set but still have the miss. I checked the plug wires and plugs all ok, the compression was 185 on all cyl. and as far as I can tell all my connections are plugged in. Any ideas what might be causing this miss? Thanks
