Important

Thanks for all the links. I can and will to a degree do some research on other forums, but I love this place and the knowledge that is here so I always start here.

The pass side seat heater light doesn't blink that I saw when it was turned on and not working. The light came on and nothing happened.

I know they require premium I was just curious if anyone was running a lesser grade gas and what the experience was. I had a 99 5.2 dakota that had in the owners manual that spark knock was normal. It suggested mid grade or premium when towing...I was pretty sure when I traded it in with 40k miles that it needed an intake gasket.

I did not hear any spark knock when driving the 5.9. I did not see anything out of the tailpipe on the drive home (I followed it).

I'm also looking at the 242 swap as I have one laying in the garage out of a 96 XJ that I parted out last year.

My dad goes to the dollar store and buys the cheap octane booster. A buck a bottle is slightly less that the difference between regular and premium. If that man saves .50 a tank he thinks he's screwing OPEC.

I have ran the octane booster in my 4.7 stroker. The stroker does not like the booster for some reason. So I run 93 octane and no problems. But I still carry the octane booster in case I am wheeling somewhere that only carries 87 octane. I come across that often in the north woods.
 
make sure you check that the input shaft gear is the same between your 249 and the 242. ZJ's used an odd output shaft. Might be able to swap gears.

The input shaft depth on the 242 I got at the junkyard in Tellico for a grand cherokee was shallower than the 242 that came out of my '91. That's why Nate and I had a disassembled tcase on his tailgate trying to make it work.

From the outside, everything looks the same, but it will stop with about 1/2 an inch to go on the transmission.
 
Speaking of transmission related problems. Cracked foex plate...
