Hello
I have a 2000 xj with automatic transmission.
The roads here are pretty snowy so I have been using 4hi around town. Is it bad to come to a stop in 4 hi. Put into park and turn off the engine? Then start up the engine with the 4x4 engaged already? Or when I need to park it should i switch back to 2 wheel and then place into park? Can I reverse in 4hi after having parked the car an leaving the 4c4 hi engaged?

the roads are only clear here tires have gone but I find I'm slipping and fish tailing in 2wd
I have a 96 Cherokee 4.0 and it will sometimes hesitate when I push the gas and if I'm not ready for it when I start from a stop it will kill. When it's doing this it also idles high and returns to idle slowly. I'm pretty sure it's the throttle position sensor but when I went to Napa all the sensors they have for 94-97 4.0 engines have a different plug than mine. My plug is shaped like a trapezoid while their plugs are rectangular. Has anyone seen this before? Should I just splice on a new plug?

So awhile back I posted if anyone has experienced a "shimmy," shacking, cavitation, like occurrence while driving a manual transmission (99 XJ - Stock)?
Here's what is going on...
if I do not hit the exact proper clutch to accelerator ratio it jumps, if I down shift (I really see it when i use 2nd gear) to help slow down, and especially when I go back in reverse! Right now it’s pretty much an ALL or nothing back up at a high rate of speed. I've had to mitigate the speed issue by working the clutch more (ie-start rolling back, push clutch back in and coast) when I have to back up now.
So to begin with I thought maybe it was a bent drive shaft issue as it seems to start the "shimmy"/rattle in the front and goes to the back of the vehicle. But I am now leaning more toward the clutch. Of course this was a part that should have recently repaired, but, as we all know...not all mechanics are created equal.
So has anyone experienced anything like this and or am I tracking the right way? I want to have a little more intel when i take it to the mech and talk to him about it.
Thanks!

so this is the hose right underneath the Map Sensor... I am hoping to find out exactly what its called. The actual hose does not need to be replaced, but I am replacing the elbow tomorrow to hopefully fix the vac leak. Just ticks me off that I don't know what the darned hose is called.
Thanks in advance!
yeah it runs over to the duty cycle solenoid and "T"s off to the Evap canister... Just don't know if it has a name other than "Hose under the Map Sensor" lol I think that every part of my cherokee tastes like gas... kind of freaked me out when I replaced my headliner.
