Check the engine oil level... you could possibly need to replace the oil pump soon... if you do not live in a cold climate i would consider using 30 or 50 weight oil. do NOT use that in a cold climate as the oil is like molasses when it gets cold.
that's only temporary. one other thing to consider is a clogged oil filter... when was the last time it was changed ?

Oil pressure drops to zero at idle. Check engine light comes on. Codes are 11,12,54. Had crank and cam sensors replaced. Wants to die when problem occurs. restarts easy. Do not hear engine clatter when...


Locate the oil pressure sending unit and get a pressure test for yourself. If it is okay, replace oil pressure sending unit. If the pressure is 0. Replace the oil pump. Probably not 0 because engine would seize.

Rough Idle, oil pressure tanks, kills jeep.


If your vehicle was purchased in the USA, it is against federal law for a dealer to sell it without a cat. If you are somewhere else, I have no idea what laws are. I have no idea what "cruising with the clutch" means.
Your oil pressure dropping may only show that at the same time the engine has stalled or is turning so slow that you are not making enough oil pressure. I would check the throttle position sensor, map sensor and idle air control valve for proper readings and operation, also check for minor vacuum leaks. It seems that your idle is too low and allowing the engine to stall. There are other things that can cause this besides what I mentioned but those are the main ones I'd check first. Testing can be done with a decent multi meter and using a chiltons or haynes manual as a guide.
Control systems need testing to get a proper diagnosis...That's one thing I can't do from here.
Do the testing and likely you will find the problem. Many larger parts stores will do a free code scan...that too is helpful.
Good luck

Oil pressure gauge goes up when car started, but then down to 0


u Have a problem with the oil sending unit. The sensor is located beack right side of the engine block. Take out the switch and make sure u have good oil PSI. Should be 6 psi at idle and around 50 at 4000 RPM. If the presure is ok replace the switch they are very cheap about 20 bucks. Please rate.

Describe your 1997 Jeep Wrangler 1997 jeep wrangler 4 cyl idle fluctuates 900 rpm to 400 rpm after warmup no service engine light but check guages light comes on momentarily when rpm gets low and oil press...


The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

2002 jeep wrangler oil pressure gauge drops


When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!

97 Jeep grand cherokee 6 cyl. idles down to 0 and dies.


any leaks in intake or exhaust upstream of the sensors, sparkplug condition and engine controls/sensors for out of range operation (including fuel pressure and condition of regulator)
IAC should be cleaned and checked as this can cause poor idle and shut down. I'm not saying not to change O2 sensors, but unless everything else if OK, it probably won't help.

Oil pressure drops at idle


If there is no engine noise associated with this ow oil press reading then replace the oil pressure sending unit on the engine, it is defective, this is common on all cars.

Low oil psi after driving 25 miles


Have a shop verify the pressure is really low, it could just be the sending unit is defective for the oil press guage, but get it checked, if it really low you could burn out the bearing in your engine, a very costly repair.
