I just tried turning the air con and off at idle and apart from a very slight rise when I turn the air con off there was no problems with idle speed. engine was still warm though had just driven it home from work so I'll try tomorrow morning as well. cheers for the help!

wwgkd....she sold a ZR1 for a Grand Cherokee? is she clinically insane?!

I'm pretty sure she is. The ZR1 needed some work to get it back into really good condition, but still. She also made my uncle sell the custom harley he had built. That actually pained me as much as the ZR1, I loved that thing.

Sorry, I'd had a few ales last night

Not saying that it IS the cause of your problem, but fwiw that solenoid I'm referring to is called an ISC (Idle Speed Control) or more commonly an Idle-speed stepper motor

For more info, perhaps try a search for it here?

Found these Magna-specific through google - maybe try some of them for a potential free fix?

For these Magnas removing the battery for any extended period (more than
10mins) can reset the computer. Idle speed is controlled by a idle stepper
motor and it takes some time for the computer to figure out how much is
enough to maintain a steady idle.

ECU will cover up faults by adjusting around them.
Most common fault is old sparkplugs, or dodgy leads. ECU has reset and now needs to readjust for the fault.

Do you know when the plugs were changed?
_____________

When the engine has no other faults, the procedure after warming up is to let the engine idle for 10 minutes.
If you can't don't wan t to fix the fault..whatever it may be, the method is to open the throttle just enough to get a stable idle, then let it idle for he 10 minutes.
You'll have to put up with a fast idle for the next 30 minutes min until the thing then decides that it can adjust back down again.
____________

The 3 litre 12 valve Magnas won't respond to this sort of treatment,
alas. The IAC valve is *not*, as it is for most cars, driven right to
the end of it's travel at engine startup or indeed, under *any*
circumstances, except when the dealer plugs in the diagnostic tool and
tells the ECU to do it. Unfortunately, only MrBishi dealers have the
appropriate tool - as you can imagine, having a captive market, it
ain't cheap to get done.

That said, you can dodge it to some degree by screwing up the base
idle (idle stop screw on throttle body), but make sure you re-adjust
the TPS afterwards (it'll be even worse if you don't!). Of course,
that may be the problem anyway (badly adjusted TPS), but it sounds
like the ECU has simply forgotten where the IAC stepper motor is
(always does when you disconnect the battery)

Btw I see lots of threads in the Merc forums, re mysterious ECU or EFI problems, with owners spending a fortune at various garages on failed 'cures' yet the problem still remains.

In Oz the experienced members always advise that the cheapest solution is to head for a Bosch service centre (factory outlet) which does have the specialist equipment and expertise to diagnose & thus repair the problem (rather than 'fishing blind' for the cure) and typically for the least money by far. (most cars in Oz use propriety Bosch electronics afaik)

I hear ya. I don't even want to think about how much money we spent on the Grand Cherokee...right now its just sitting down at the mechanics has been for a good month or two. nothing wrong with it right now but better not tempt fate dads done the sensible thing and bought a diesel hilux surf.

yeah. chrysler as much as said that out of every 100 jeeps they make, 10 will be as good as anything from toyota, 10 will give the owners persistent trouble and the rest are variously in between.

cheaper to run two porsches than a ****ing jeep
(use less fuel to boot)

I've been trying to find the history of this whole jeep thing on here but my current computer is so slow that searching the forum takes forever. What Jeep did you have?

[clutch-monkey]

cherokee of some kind, the shit kind with a V8
friend had a wrangler that was new in 2005, had the old I6. issues with that car too, which was a worry, because if it did break down chances are you were somewhere generally inaccesible lol
both of them used retarded amounts of fuel.

[IBrake4Rainbows]

It's true. Even my Volvo, which has the apparent aerodynamic properties of a Brick, uses less.

Sorry, but It's like a land rover Defender - the myth of toughness and go anywhere is VERY different to the reality

Australia, Europe, South America, North America, Central America, Africa

Reality = TSONGOLOLO 6 years of international touring (no base) in this Defender poptop

We chose a Land-Rover – again – because, well, we wanted a tough and robust vehicle with a reputation for good payload and fuel economy, most armed forces around the world use them (which says something) and although the basic ‘style’ has changed little over 50 – 60 years, under the bodywork (still aluminum) Is a Modern up – to – date machine with permanent 4.W.D. and turbo intercooled diesel bits and pieces! The Defender 130 Td5 suits our needs, can carry 1.5 tons and takes the Trayon camper easily, we cruise along at around 90 K.P.H. and use ± 11 Litres of diesel per 100 KMS, we looked at all the other 4.W.D.’s also but at the end of the day, when the dust had settled, the calculations done, the Defender won, so we ordered one!!

[IBrake4Rainbows]

Please don't get me wrong - they are tough vehicles. My father managed to woo my mother using a series II....

Their strength is their ease of repair, not their reliability. And certainly not in their build quality. The problem of course is those who buy these vehicles for Posing purposes, expecting the rugged nature of the vehicle to translate into slim panel gaps and trouble free motoring

On the defender thing, telstra did a experiment a while back and bought a heap of them and set them up for their remote techs in the territory and far north sa. They literally fell to bits on them in 6 months, they have now gone back to Nissan Patrols.

[Spastik_Roach]

funny thing is Nota I did accidentally leave my lights on a couple of weeks back and had to go get the ECU reset (only 30 bucks at local Mitsubishi dealer thank god). But it was cutting out like this before I did that. Its been fine all day today though so its possibly a loose wire thats getting knocked in and out intermittantly. Might do a bit more in depth look into whats causing it this weekend. cheers for the advice!

Always been a cruiser man...

Ahhh. Yeah, I don't consider a cherokee a real jeep anyways. Plus most of the V8 jeeps had a reputation for not working so well. The I6 is usually pretty bullet proof which is why they used it for 50 years, but mileage sucks. Only one of the guys that I know ever had troubles with a wrangler, and it was one of the TJs ('97-'06). Well, I know a guy that raced CJ5s at pikes peak back in the day with a 392 hemi that used to blow engines all the time, but that's a different story. Sorry to hear about your troubles, though.

It's pretty hard to find a vehicle with worse aerodynamics than a jeep. It's not just a brick, it's a flying brick, especially when lifted and combined with wider tires. I get some pretty noticeable lift at higher speeds, and going 100 is plain scary. But to slow down all you have to do is lift off the gas and it's like hitting the brakes, so that's nice, I guess.

Says you. Defenders have always left me a little underwhelmed, and stock jeeps come with tires from wenchels, but put just a little money into one and you can go more places than most people would ever want to. Aside from the one guy in my 4x4 club, I've never heard of people having that much trouble with jeeps, other than the JKs, the most recent model. Maybe the jeep gods just don't like aussies.

quite a fan of trayback diesel patrols, used them extensively on sheep properties, grandpa has one that i still use today. shits all over the cherokee

the engine on the wrangler was fine, rock solid as you say. the interior was shit but sorta in that suitable way in that you can hose it all down lol.
it's just everything electrical and the ancillaries appeared to be made out of tin foil and cardboard.
which is worrying because it really does have nice offroad abilities even stock standard.

edit: also, solid mudguards. WTF

my theory is they just can't take actual tough conditions..none of this temperate zone bullshit probably why it's hiluxes and patrols all round..

Ahhh.

Solid mudguards?

Haha. Yeah, this coming from the land of no snow. Back in the dark days when I was living in california my 4x4 club would make runs to death valley in the summer and up in the sierra mountains (easily find trails running well over 7,000 feet above sea level) in winter and we didn't have trouble.

In all honesty, a diesel hilux would be a pretty good alternative but we don't get them here. I'd probably still go with a jeep out of sentimentality and fanboyism (I bleed diamond plate.) I have seen jeeps converted to diesel and if it wasn't so easy to put a hemi into the newer models I'd seriously consider that.

[clutch-monkey]

Ahhh.

Solid mudguards?

yeah the wranglers have been coming with plastic mudflaps rather than rubber ones. needless to say all four got ripped off by boulders on our first offroad trip lol

Ahhh.

Solid mudguards?

Haha. Yeah, this coming from the land of no snow.

pfft snow
if dad can run a GT3 in 6 inches of snow on performance tires it can't be that bad for a 4x4

In all honesty, a diesel hilux would be a pretty good alternative but we don't get them here.

top gear says they're indestructible
took me 20 min to break it
