No worries jlenko, my feelings aren't hurt that easily. You are right, I have no idea how to tune the ecm nor is it easy to get to in this car. Since its a 97 there is no obd2 port so they did the drive test. The way I tested for codes is by shorting two pins of the diagnostics in the engine bay and counting cel flashes, as per the jzx100 forums.
Also from my reading on the same forums spark plugs for this car/engine should be changed if the regular ngk's are used, every 5000ish kms. Apparently this is only the case for the regular plugs, the ones with only one little side sticking up, platinums last longer. So the reason i mentioned the plugs is because when I got the car I checked them, and they're not platinums, but they looked new, with no corrosion or anything so I left them, and now its been ~4000kms so maybe I should go platinum? Since the issue with hydrocarbon can be linked to unburned fuel, I thought maybe it had to do with the spark plugs not igniting properly?
Also just to clarify, I didn't think the silencer would help, I just mentioned that it was inthe exhaust at the time of the test in and effort to give as much detail as I could
I'm not looking for a quick fix but I would rather fix things like spark plugs on my own rather than paying a shop to do it, if that could be the issue. I drove the car for about an hr or and waited on the lineup for about 10minutes.
