Hello, all. About a week ago I was climbing on the freeway in my 1999 4.0 5-speed manual and it started skipping. By skip, I mean I would very briefly (like .1 seconds) lose power and then regain it. It did this 10-15 times in rapid succession as I was overtaking a semi. My first though was the fuel pump. I just hit 213,000 miles and am on the original.
Then on the ride home, my passenger and I both noticed that our sandaled feet were cooking down in the foot wells. I've been driving this jeep with the whole inside of the tub bed-lined and carpetless for about 10 years, and never experienced this kind of heat.
In the last week of daily driving, the heat coming from beneath the dash has not subsided. Based on the digging I've done on the forum, it sounds like the heat is coming from my catalytic converter. The other tidbit I found is that faulty fuel injectors can cause an overly rich mixture which causes the cat. to overheat. On occasion I've noticed a fuel smell in the air while driving, but I am kind of a hypochondriac with my car, so who knows if that's legit or not.
Could a bad/failing fuel pump cause a fuel injector(s) to fail and create these symptoms? I would be thrilled if this is just a bad injector I can replace, but since the pump is right in front of the injectors in the system, I'm worried the failure is happening upstream.
Going to do some more office chair research on testing and replacing fuel injectors.
Thanks in advance for any guidance you can provide.
