What model year and fuel system/engine is this? Does it run well before it dies?

So, I took the battery out of the remote, made sure the doors were locked and went to bed. A few hours later, I check the car and the doors are unlocked again.

This typical? Seems like the control unit for the keyless entry in the Jeep is acting up to me.

Is there a way that i can cut the power to the keyless receiver to disable it while still having the power locks work (pushing the lock/unlock button on the door panel)? I have been searching online and can't find a fuse to pull or the location of the keyless receiver for the Jeep.

Any help will be appreciated. Thank you

You'll want to try the Grand Cherokee section. This here is for Cherokees dating back to 1984!

No hissing or anything from exhaust gasket, no leaking from injectors that I can see. Fuel rail pressure was fine yesterday before changing injectors out.
Now this has turned into stumbling idle and the transmission doesn't want to shift. Then it threw a CEL. I've gotta let the parts store open up down the street to read the code.

Any sense in wiggling it around and cleaning, or is that a thing to just replace?

From what I have seen, it's not easy to get at. Therefore, I would suggest replacement, probably with OEM only.

I unplugged the TPS wire, and its idling & shifting seemingly fine. I imagine that points to TPS then. I'm going to let it dry out all day to see if I got some powerwash water in it from cleaning the engine before swapping the exhaust, otherwise I'll order one. PITA! ha.

That is for a cherokee though.
C16 fluctuated between 88 and 107 ohms (C14 and C15 were both at 11.5). That would indicate that the #1 solenoid failed, correct?

Is it possible to wrap the exhaust manifold with heat wrap while it is in the car or would one need to remove it to do so.

Just thinking about all the heat generated in the engine bay and wondering if that would help.

Looking at the manifold, looks pretty much impossible to wrap in place.

Just wondering if anyone has done that.

So random question. I need to replace the rear main seal in my 96 zj 4.0L. It has about 250K miles. Is there any reason to consider replacing the pump while I'm in there, or is the lifespan for the oil pump in these more or less indefinite?

Thanks in advance for the advise.

Ah ha! Yeah we washed the manifolds to get all the grime off since my VC leaks a hair. I unplugged it and let it dry out for a while and drove it without it, and it seems to somewhat have fixed itself. Had a store run the codes, got P0740 & P0122 which both seem related to the TPS and TCM lock out related to the TPS. They couldn't clear the codes with their tool, any way I can? Yank the battery leads for a few minutes? Just want to see if it comes back. Going to disconnect all the plugs and let them dry. Might have gotten some water in there the other day.

Pretty much indefinite as long as it's not abused. Most people just go straight for the gaskets without touching the pump or the bottom end. If your engine is in good shape I'd be fine leaving it.

Yes leaving the battery out for a while should dump the codes. The TPS internals getting wet is the real problem - it'll take a few days to dry out at a good temperature. If you've got a heat gun or hair dryer you could give that a shot.

Use your accessories, sensors, flywheel/flex plate and manifolds. You'll need to plug the hole in the back of head where the old temperature sending unit lived otherwise it'll shoot coolant everywhere
