Question about Jeep Wrangler

2 Answers

My 1991 Jeep Wrangler 4 cylinder 5 speed manual transmission, dies when stopping at intersections etc... It starts right back up and has no problem idling until I am slowing down to stop. It does keep running if I am able to get it into neutral and feather the accelerator pedal down to an idle.

There could be a number of culprits. My first suggestion is to replace your fuel filter. It may be so clogged that idle speed doesn't draw enough petro to keep cylinders happy. Your fuel pump might be on the blink too. Lastly, you might want to inspect your Throttle Body Injector (TBI). It, too, could be clogged and starving the engine of fuel. Somehow, you've got a fuel starvation issue at idle speeds. Good luck.

Check spark and fuel pressure. One is failing and must determine which to proceed further.

2000 jeep wrangler are sythetic lubes used in axils and trans


Hello grega1967, your Jeep Wrangler came from the factory with gear oil in the axles and manual transmission, but the transfer case uses transmission fluid. It is a NP231 and your axles are Dana 30 in the front and Dana 35 in the rear. They should have a 4.10 gear ratio due to you having a 2.5 liter 4 cylinder.

I hope this helps,

How do you bleed the clutch in a 1991 Jeep Wrangler?


If replacing just the fluid, you should gravity bleed it by opening the valve at the side of the transmission where the line goes in to connect with the slave cylinder. Be sure to stand by and keep the tiny reservoir from going empty during bleeding, or you just make things worse. Assume you replaced parts. Is this right or wrong?

Or are you just trying to restore performance in a poorly operating system? Would help TONS to know these details, and how much you know about bleeding, etc. If you are trying to bleed a new slave cylinder, it can take 600 to 1800 pumps of the clutch pedal sometimes to clear it out manually. If you want instructions on how to bleed in with vacuum assistance, please post request comment to that effect.

Talk to you soon. TT
