Has a rebuilt TUPY head from a Wrangler. Replaced about 3 years ago. Should not be any compression/valve issues. When I pulled the plugs yesterday, they had all worn evenly and looked nice.

Has new Mopar Cam sensor. The crank sensor is a couple of years old but it is Napa, not Mopar. I am putting the OEM ignition rail back on today. I replaced it with Echlin a few years ago trouble shooting, but it wasn't bad. It is in my garage. Could be a bad injector. Very possible. And it does...

It is not a loss of power, so to speak. It is more like the drivetrain disengages for a split second. Or all spark is lost for a brief moment. Or the fuel is cut off for a split second. This is more of a brief hiccup. The CEL NEVER comes on due to this issue and it has NEVER thrown a code due...

Thanks again for the tips (blondejon). I will cover some of this with the plugs/rail/TPS coming up. I put new filter, fluid and gasket in tranny two years ago and fluid is nice and pink and at proper level. Fuel system could be the issue. Especially fuel filter.....except the obvious question...

IMHO: The whole dielectric grease thing is over-rated, unless you are trying to waterproof your connections. Packing the crap out of electrical connections with dielectric grease is great for vehicles that are going to go under water. But I don't use dielectric grease at any point in my ignition...

(Edited to reflect NGK comment, because he is correct) The Jeep 4.0 calls for cheapo, CHAMPION/NGK brand, basic plugs. This is one of those points that I will argue with you on. The 4.0 is a simple engine. It was DESIGNED with the Champion plug. The FSM calls for Champion/NGK for replacements...

I would not fool with a 0331 head. They are defective. Shaving it and doing a valve job does not address the inherent weakness of the head. And the TUPY head WILL NOT give you the same problem. The TUPY head was recast with thicker walls between the trouble cylinders specifically so it WOULD NOT...

No codes AT ALL. Go figure. Since I have replaced my head due to misfires, I recognize what misfires feel like. This is much more sudden and more clunky. It is like EVERYTHING disengages for half of a second. The nose of the Jeep even dips for a split second. It sort of goes "clunk," stops...

Thanks MD. I was thinking torque converter or TPS. $90 for an OEM TPS. I suspect that is my next move. Thanks again.

^Cobalt bit, not carbide. Oops.

Cobalt: Yeah. I did. Thanks!

My 2-cents? Slow down. Be easy. Gaskets should be tight, but not over-tight. If you are new at this, run every bolt in with your fingers as far as you can. Use a ratchet to snug them down, then add a 1/2 turn with a wrench. Climb under the next day and look for leaks. Fluid will drip off of the...

BTW: You are almost certainly going to spin off the heads of the bolts for your upper, rear shocks. At least one of them (there are two on each side). Spray them with PB B. from the bottom every night for a week (don't spay PB inside the cab. You will never get the smell out). Then hope for the...

If you want to part it....contact me. I might pay you cash for it. As for purchasing a head: Use the interwebs to get junkyard telephone numbers and start calling. Have it shipped. This will cost you more than $600 in parts and rebuild. Plus the cost of swapping out heads if you pay someone...

A good XJ sells for $10,000 and the prices are going UP, not down. Just saying..... BTW: I mean a GOOD XJ. Mine is a 2000. Leather front seats. A/C. Cruise. Aftermarket bluetooth radio. Roof Rack. No dents (has minor dings). Good carpets. No damage to interior. Minor rust (mostly under the...
