Ok, so I am not a Jeep guy, yet. But it don't mean I can't think or use my reasoning cap. And two issues seem to converge into a solution, maybe.
Issue one, is there was a tremendous amount of heat coming up, via the cat converter, through the floorboard. My girl first recognized it, and presumed I had the heater on. I found it even more noticeable coming home from work one day, ( a rough 36 mile commute) and noting after about 10 or so miles a huge amount of heat coming up via the floorboards. I climbed under, noted the cat was basically right under the passenger seat. As well, I have a heavy steel skid plate that sandwiches the entire thing, and therefore double the radiant factor.
Typical solutions ran to the idea of a reflective / insulative material placed under the carpet, etc., as apparently this is a Jeep thing. But although I could feel the Jeep quirk vibe, I was not thinking the sheer amount of HOT I was experiencing could be "normal", even as a quirk. But, it was a project that was not my number one priority to fix. So...
So, week two of Jeep and a few days off meant time to take care of some more issues (post throttle body cleaning last week). Wires, plugs, cap, rotor. The picture below is the old plugs. Not in real good shape. They came out easily enough, but moisture had evidently been a problem at some point in time, and it had not cooked off by engine temp. I surmised that with plugs looking like so, the wires were likely not all that great, and figured once the change over was done I would see some improvements more than ordinary. Went back in with essentially "stock" non performance parts. I did insure, however, I went with non aluminum contacts in the cap.
Since the tune up, floorboard heat has been more of a degree I would call "Jeep quirk" and not blast furnace. My assumption at this time is that at least one cylinder was getting a misfire or similar and dumping gas out the exhaust valve. Hence the high cat temps. So...if your Jeep is:
Very high floorboard temps + possible plug or wire issues / age / deterioration
They may be related.
If I note that floor temps rise back up to crazy levels, I will edit this post to show it.
As well, I had noted that, prior to the wire change, fuel consumption had been HIGH. I know it isn't a Prius, and I am not sure as of yet what is normal for this particular Jeep, but it did seem a bit over the top. And, engine water temp has gone down a bit SINCE the change, sub 210, when it was running 210 prior. Can't say for gas mileage,yet.
