Dorman with heat shield along with Felpro gasket has been on since last year. Going strong so far. I have put 2000 miles.

Can you send me a link or the name of it so I can find the replacement harness? My fuel gauge stopped working. Turns out mice chewed this wiring harness coming out of the fuel tank. I’d like to find a replacement so I can splice into the existing wiring.

I recently ran LiquiMoly Pro-Line Gasoline System Cleaner in the tank for about 30 miles. This morning when starting the Jeep, I noticed my speedometer didn't work, The check engine light came on which reads P0500 (Vehicle Speed Sensor A). I attached screenshots of live data while the engine was...

I have a 2000 Manual 4cyl TJ that is new to me. It finally snowed enough here for me to put it in 4H. I noticed when I pull the lever nothing shows up on dash. Should 4H be lit up on the dash? I don't notice any difference in the jeep when I pull the lever. whats your list of things that I need...

@C.J. Roberts Thank you

@C.J. Roberts isn't that valve for checking fuel pressure in the fuel rail, and is not connected to the vacuum system?

Thank you for your response. this is where the valve is, correct? mine is a 2000 TJ 2.5L manual.

I have a smoke machine and would like to see if any of the hoses or the PCV valve is leaking. I am doing this to learn and see if there are any possible cracks that can cause a vacuum leak. Where should I hook the smoke machine to? would you just poke a hole in a glove and place it directly over...

MAP reading is 4.9 psi which means its running lean. I think there may be a vacuum leak as @NskLJ noted.

I did not know trip odo reset! I did download GPS speedometer & odometer app to check.

Yes it does! what does it mean? FYI fuel sys 2 is just blank. edit: so from what I gathered, it means the fuel system on bank #1 of the engine is in closed loop which means normal operation of the engine, therefore, no issues with the oxygen or mass air flow sensors. Am I right @NskLJ ?

I couldn't find Mopar O2s on RockAuto for some reason. Here is what I found on Advance Auto. What do you think of this? https://shop.advanceautoparts.com/p/ntk-switching-oxygen-sensor-4-wire-14-long-heated-direct-fit-23506/20474402-P?searchTerm=NTK+Oxygen+Sensor

it was around 13-14

Jerry, I will order a new upstream o2 sensor regardless to be safe and it is good maintenance anyway.

I took the jeep for a drive. Ran live data, here are the results: ECT is 206 F MAP 4.9 O2B1S1 (V) 0.6 O2B1S2 (V) 0.1 I have a smoke tester which I will use to check for engine vacuum leaks.
