Misfire or Distributor issue? Bad Vacuum leak. (2 Video)
I made a post a few days ago but didn't get any answers. I'm not exactly sure what the problem is with my car, so i posted some youtube links. I have a 1994 B18C1 [GSR] in my 1999 EK. I have a jumper harness for OBD2 to ODB1. There are other conversions in the engine harness as well. The car currently has an OBD1 Dizzy, but I was told that I needed an OBD2 dizzy. I changed the spark plugs and wires to NGK, but that did nothing for the problem. I checked the CEL codes and they are:
#8 - Top Dead Centre Sensor
#23 - Knock Sensor
#41 - Primary Oxygen Sensor Heater
One of the videos is of a pretty bad vacuum leak and I can't find the leak. I sprayed the injectors, throttle body gasket, intake manifold gasket, and some other hoses with carb cleaner but i didn't notice any idle change. Is it possible that the leak has something to do with the Air/Fuel mixture and is causing my engine to run like ****?
Here is the "problem" with my car. It was difficult to record and steer the car so I apologize (ignore the music too lol). I had my foot completely down to the floor, and you will notice the poor acceleration and "bogging down" or "misfiring" issue it has.

#8 will do exactly what you're experiencing with the missing/bogging, sadly that's one component you can't change out, new distributer time. I guess if you're willing to hack/splice in a new one you can it's not a good idea tho.
as for the vac leak sounds like the TB gasket altho if you look at how the gsr intake manifold is constructed I'd be willing to bet it's one of the plenum gaskets. the 02 is a cheap fix get a o2 off of ebay for 30-50$ have one on my track car even... yes they work fine just wear out faster. knock is probably related to how your car is running, misfiring/bogging.

I think you're right about the plenum gasket. The leak is probably coming from somewhere in the bottom of the intake manifold where I can't reach with carb cleaner. Thanks a lot man. It's about time I get some advice for this
