SOURCE: 2004 Jeep Grand Cherokee. Keeps stalling, engine

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

SOURCE: Install a 05 Jeep Liberty 3.7 in a 02 Liberty

BEFORE you put the engine in you must convert it with your old engine's crankshaft position ring and it's pick-up sensor. This ring can ONLY be changed with the engine upside down and out of the car. All rods must be disconnected, all mains are part of a cast saddle that must be removed, the front engine covers and all the timing chains must be removed, and finally the crankshaft must be lifted out and the ring must be hammer-unscrewed (impact screw driver, but I forget now if the taper-headed screws are allen, hex, star or phillips). DO NOT WASTE YOUR TIME REMOVING THE HEADS. The ring is ENTIRELY different than the one the computer system on the 02 Liberty can recognize (this is what triggers your spark timing). Next is the magnetic pick up 'wheel' located on the front of the passenger's side of the over-head camshaft. This magnetic cup wheel triggers the '02 fuel injection system (don't un-magnetize it). Lastly, the '02 plastic intake manifold (w/ O rings for seals) for the '02 has an additional port, this is an easy swap-out. Mostly there are no gaskets- the finish is so fine they just use a factory sealer (comes in a tube). Buy it, it's cheap enough and it matches the factory's specs. Taking the engine back out/in is NOT fun, but with the engine on a stand, and with no time constraints it's managable (but still not fun). I made that exact engine swap myself and went through a lot of anguish learning all of this. By-the-by, these engines will NOT tolerate dirty oil. DO NOT EVER try and stretch out your oil changes, because they run really hot (due to the windage tray that prevents oil mist from coating the engine's internals) an ash will form and goop up the insides. The fine oil pick-up screen (drilled plate) will always clog up. If it's been a long time since the last change and your engine is still running fine, when you get around to putting in new high detergent oil it sorta un-sludges the goop and REALLY coats the pick-up. DEATH BY SUFFICATION. If you're ever at this point (no damage yet) I would suggest doing the oil change (before there's any knocking or signs the engine is failing) and I would do 2 more oil & filter changes @500 miles each; hopfully you'll dislodge the ash/sludge and get it out of the engine. Once damage has started it progresses very quickly- this engine is not very tolerant. Your oil will be gold color, and yet your enging will sieze because it can't 'get to it'. BEST OF LUCK- this is very do-able, but you might first investigate if you can swap out the engine management computor and wire harness and maybe avoid all of this above mentioned wrenching. No back ground info here, plus I didn't have access to the vehicle the 05 engine was snatched out of- sorry, and good luck again. One last bit of advice- I bought a zero miles engine from a National Highway Admin. crash/test vehicle. When I broke the engine down ALL the timing marks on all three chains were not aligned and had to ALL be set- I guess they might do that to prevent the parts from re-entering the 'system'? Or, some dumb s__t at the factory was new and/or pi__ed-off and this engine was just plopped in the donated/untitled crash vehicle rather than ripping it back apart and re-assembling it. The damn Jeep fired on the second crank and is running fine now (2 years later). Ciao4Now, Brian Fahey

SOURCE: are the 3.7 liter jeep liberty known for head

any vehicle can have any component fail at anytime. The only way to know is to have it inspected for the correct diagnosis if your experiencing problems. If you want a second opinion because you don't trust the first one then your only going to get that at a repair shop.

Check the wires at the back of the harness plug for any breaks. Some times they break inside the coating, so pull on them. If they stretch, it broke.

2004 JEEP LIBERTY KEEPS COMING UP #6 cyc miss fired.


When I had a misfire and could not find the problem, I would drive my car at night to an area where there were no lights near by. I would leave the engine on and open the hood. You can see if there is any arcing from from your spark plug wires or any electrical wiring to the engine block. Also, you may want to consider this: How long has it been since the spark plug wires were changed?

How to know if pcm is bad


The PCM would probably not keep the engine from cranking. If the check engine light does not come on when you turn the key switch on, I would check to see if all of the fuses are getting power from the key switch first.
Could be a problem with the key switch.

I have a 2004 jeep liberty, what is EATX?


Try unhooking your battery. It should reset the light. If that doesn't work it could be the relay again. I have had that happen to me with my 2001 Expedition. Was told it was caused by me giving someone a jump and it caused the service engine soon come on.

Jeep Liberty 2004 sport gas cap not sealing


You can get the silicone grease at automotive and hardware stores. Apply to rubber seal on cap about every 2 to 3 months. This will ensure a seal so that the engine light doesn't come on. Worked great on My 2008 Liberty.

2004 Jeep Liberty-the Oil indicator light comes on and will stay on. Turn off car immediately as the book indicates, let it sit for awhile, turn back on--light is off. Drive a few miles, light comes back...


Double check how much oil is in the engine, it could be coming on because your low on oil. I can only think of two other possibilities either you have a bad oil sending unit or you have a problem with your oil pump.

My dad's Liberty will start with no problem but then the engine light flashes 5 times and then will stall once it hits second gear-please tell me what the 5 flashes mean


I would take the vehicle to your local autozone and have the codes checked and that can tell you with a lot more accuracy what the issue is.
Thanks,

My speedometer quit working


Find out why the check engine light is on, and this will most likely lead to your speedo working again. Sounds like a bad speed sensor somewhere.
