#527 of 731 Rough Idle After Engine Rebuild
Jun 01, 2009 (2:02 pm)
Hello...I am new to this group. I have a 2001 Jeep Cherokee 4.0 4X4. I just had the engine rebuilt by NAPA. The new engine is installed and connected. I started it up and it was idling rough. I noticed some vacuum leaks on the injectors so I replaced all of the O-Rings. That seemed to fix some of the problems. I checked the onboard computer and there are not error codes. The engine sounds great when you run in above 1000 RPM. It just when it idling is when it is rough. There are no air leaks. All of the sensors are connected. Before the engine died(before it was rebuilt) it ran and idles normally. Does anyone have an opinion?

sounds as if you still have a vac leak
i would get a vac gage and see what the vac is at idle should tell if have vac leak
#529 of 731 Intermittant starts
Jun 02, 2009 (5:15 am)
I have an 05 Jeep Grand Cherokee which intermittantly starts. The dealership just tells me they can't do anything until it is NOT working and, as life would have it, everytime they have it, it starts. I replaced the ignition switch and still have the problem. What do I replace next? What other parts could be the problem? I turn the switch and nothing happens. There is no sound, and the engine does not turn over. Thanks.

Thanks for all the replies... You have to wonder exactly how anything gets fixed nowadays with so much stuff that could go wrong! Anyway, I had another reply from another site. This is from a 15 yr certified Jeep/Chrysler mechanic. I'm going to try this first and go from there. Maybe it will help someone else too... "'this trans had problems with the dipstick tube letting water into the trans-usually need lots of water for this to happen--my suggestion is get the trans serviced--make sure to use the mopar fluid-this trans is picky-you may have to have it done twice if the fluid is bad--when they pull the pan if it has water in it the fluid will look milky--if that is the case you will need an overhaul--the clutch discs are glued on with water based glue--if not then try driving it for about 100 miles if the shudder is still there you will need a new torque converter-also make sure the trans controller is up to date'
#531 of 731 4.0 misfire: ignition coil
Jun 04, 2009 (11:48 am)
I had been getting a check engine light for some time and poor performance, sputtering, etc. (2001 4.0L) The codes read as a misfire on cylinder 6. I changed plugs, looked over the wires. No good came of that. The Jeep was in for another issue (radiator hose burst) and the guy working on it said he was a dealer Jeep mechanic for 15 years and that the problem was always the ignition coils that are in the long bar that plugs into the spark plugs. He was great: said I should do it to save money. The coil pack was about $125 and I installed it in about 30 minutes. Now it runs great.
Still the check engine light is on. Will the light go off eventually? How do I reset the codes so it goes off? or Does the fact that it is still on (only driven 10 miles) mean that something else is wrong?
#532 of 731 '05 WK 4.7 misfire when throttle is barely open
Jun 05, 2009 (9:41 am)
My misfire only happens when the throttle is barely open, when I stomp it it's gravy. The other day it shut off when pulling up to a stop light, started back no problem. I have had a few codes come through, random cylinder misfire and misfire in cylinder 8. I changed the plugs, TPS, and coil-pack for cylinder 8. Over time the misfire has gotten worse the codes have changed slighty, random cylinder misfire, fuel system too lean, fuel system too rich. Just took it to a dealer, they said to change the plugs, and run a fuel induction service. Any thoughts?

Help. I purchased a 92 jeep Cherokee for my grand daughter since her parents could not afford to buy jer a car. I am 66 years old and on a fixed income as well as being in poor health, but she could not hope to get a scholarship to college without transportation. This jeep had multiple issues which i repaired. The reason it was sold to me for $500 was a lot of noise in the engine when it was running. All the torque converter bolts except one had fallen out and were in the inspection pan. Not the water pump is squeling and i have no clue how to replace it. Please help me with some advice. I am mechanically inclined but have limited mobility, but can not afford to hire this out.
#534 of 731 2001 Jeep Cherokee Aniv Engine Idle Problems after Rebuil
Jun 08, 2009 (1:52 pm)
Well I after trying to figure out why I was having idling problems...I realized that one of the spark plugs had oil on it. So I am assuming that it was not firing correctly on that cylinder. Also, before I could do anything else....I started to have white smoke come out of my tail pipe..head problem? Also I noticed that there is coolant leaking between my engine and tranny (around the bell housing) I could not find a leak on the back side of the head...just in case it was leaking from the gasket and seeping down into the bell housing. Any ideas anyone?

The water pump is pretty easy to replace (Easy on an inline 6 cylinder 4.0) Take both the fan shroud and the electric fan off. Should be 4 screws. Then you have to loosen the power steering pump so you can free the belt. Then there are 5 bolts on the water pump. Remove those then clean up the surface to prepare it for the new one. Make sure it is very smooth..this way you have a good seal when you put the new pump and gasket on. I always like to take a little bit of RTV sealant and apply a thin layer to the new gasket before applying. Also while you are messing with stuff...I would go ahead and replace the thermostat which is located above the waterpump. You will see the radiator and heater hose connected to the inlet. Take both of those off and remove the two bolt. Clean both surfaces and install the new thermostats. Hope this helps you.
