04 WJ 4.0 mid rpm misfires clears on restart 02 Jeep WJ with 4.0
The engine will multiple cylinder misfire if rev over 2.5 rpm. A very rough misfire will continue until engine is restarted at which time it clears right up.
I connected Torque Pro app with a bluetooth adapter and shows o2 sensor data are seemingly good. I dont often rev the engine but have never had this issue prior to changing both upstream o2 with NTK a week ago. Again the data seems to look okay from those.
Fuel pressure shows a solid 50 psi at fuel rail. There is a slight leak down with engine off but confirmed it is not a leaking injector, likely failing 1-way and doubtful it s part of the problem.
Installing DC-DC charger for trailer charging We are full time RVers with our Grand Cherokee and 23’ travel trailer. We have 2 190Ah lithium batteries installed in trailer that I would like to charge while driving. It appears that a dc-dc charger is my best option. Does anyone have detailed instructions for installing such a thing? I assume I will need to upgrade the wiring to the 7 pin trailer connector.
Thanks
Brake booster interference with Clifford dual Weber setup

Brake booster interference with Clifford dual Weber setup I have a 1983 CJ7 with a 4.2 six cylinder engine that I have done some modifications to and I am seeking some help with the finishing touches to complete the job. The modifications include: Clifford dual Weber intake and carb setup, Clifford 6 into 2 header, Iskendarian 270 camshaft, .060 milled off the cylinder head. The rest of the engine is freshly rebuilt but stock. I put the body back on the frame last week and I found that the brake booster will not clear the rear carburetor. The booster has a bracket that spaces it out from the fire wall about 3 . I have read through some previous threads that the bracket is used to help the booster clear the hood when it is closed and it also has a linkage to multiply the effort from the brake pedal. What is the solution to this problem? Is there another brake booster that I can use and eliminate the spac
Rear Main Seal? So this has been an issue for a while but honestly seems to come and go in intensity. Small oil stains and drips on pavement when I park, from rear of engine. Also, when driving on highway, when I go to an exit and start slowing down I get a light plume of grey smoke out the back, presumably from same oil drip hitting the exhaust.
Fairly small, don t need to refill oil very often and have gone between oil changes without having to add any.
So, does this sound like the RMS? Also, is there any long term danger to not getting it fixed? Just so much money for something so simple that doesn t seem to be affecting anything other than the stain on the street and the occasional annoyed driver behind me driving through a light cloud of oil smoke.
Hello and thanks
