96 Jeep Cherokee 4.0L trouble code 43
After driving about an hour and a half on the freeway, we stopped at a
gas station. When we left, it started fine. We went another few miles
(city driving) and stopped for 15 minutes to half an hour. When we
started the jeep, it ran rough (but a consistent rough). We pulled
away and for about 20 feet, it kept running rough, but came out of it
and ran fine. On the way back home, the check engine light came on,
and I got touble code 43 which is a misfire. I've seen postings that
say Jeep had a bad/weak batch of valve springs during 96 and 97. My
question is - does that sound like bad valve springs? Or should I
check elsewhere first. I haven't checked anything yet.
Thanks,
Wes

Could be a loose coil power wire:

I associate weak valve springs with high RPM float, and would run
perfect at idle or Cruising speeds.
