Newcastle Jeep mechanic?

[Jeepkook]

Hello

I’ve just moved to Newcastle, NSW with my XJ and looking for a mechanic who knows their way around a XJ Cherokee and was wondering if anyone knew of anyone?

My 2000 XJ has a rough and low idle as well as an occasional misfire on cylinder two, I’ve been trying to sort it out myself but haven’t solved it and could do with a hand.

Cheers

JeepKook, thats what were here for. No need for an expensive mechanic charging you $125 an hour.

Your Jeep is OBD2. For $15, get yourself an ELM 327 OBD2 reader. For $5, get the Torque Pro app. You can then plug in an get all the readings, codes etc for your Jeep.

I can tell you what the normal items are. Yours is a little different than the older ones like mine, as it has a coil pack.

A rough and low idle can be your IAC sensor which may need cleaning. This is your Idle Air Control sensor. Lots of YouTube videos. Easy and free to clean.

Have you done the normal tune up stuff? Plugs, air filter, checked vacuum hoses? Misfire could be coil packs.

If you start with the Elm code reader, it should give you some codes.
Also, here is a way to check your coil packs easily...

You Tube

Other than that, i am in WA and can't recommend a mech over your way, but the boys on here usually get members cars up and running smoothly....

Cheers,

I live in SE Newcastle area...where are you located ?

I know an outstanding auto elec at Belmont, and a very honest mechanic at Bennetts Green.

Not many people want to work on a 20yr old Jeep

I agree with Alex..you must obtain a code reader...pay for itself many times over.

Then I would check and swap spark plug and coil pack at least, that is what I do with coil-over-plug engines with a misfire

Hi guys

Thank you for the info and suggestions!

I'm located in Islington. I've asked around at few local garages here in Islington and Wickham and have found a mechanic who owns a XJ & WJ. Mark at Paul Bramble automotive, 8 William St, Maryville NSW 2293.

Mark has helped me out to find the issue of the misfire and very rough idle. It looks like the head gasket has failed between cylinders 2 & 3. Pressure on both was around 60psi. So it looks like I'll be replacing the gasket and getting the head machined.

Since owning the XJ for 5 years I've never had a overheating issue so maybe the gasket has just been slowing failing from a issue before I owned it? It was driving great, drove to the shops one day a few weeks back, started it up to drive home and was running rough.

Around the corner in Wickham are The Head Men who specialise in machining heads. Jason & Aaron there were also very helpful and answered heaps of my questions.

Both Mark and the guys at The Head Men reckon I could do the head gasket myself. Having never done this on any car before, it'll be a first time!

My'00 XJ has only done 157K. I know this year has issues with the cylinder head cracking. Hopefully its all good. But in case its not does anyone know where I can get hold of a Tupy stamped cylinder head here in Oz? I don't really want to pay for the shipping from the states!

While not wanting to admit it could be a head gasket issue I replaced the following parts:

• OBD2 reader & torque app ( P0302 code - cylinder 2 misfire )
• Cleaned throttle body
• TB gasket
• Air intake hose clamps
• Performed a smoke test (only found a leak around the TB shaft)
• Checked for vacuum leaks with carb cleaner
• Vacuum pressure test ( reading was jumping around in the red)
• Injector diode test
• IAC sensor
• MAP sensor
• TPS sensor
• 2x 02 sensors
• CPS sensor
• PCV valves, grommets and lines.
• Cleaned air filter
• Battery
• Checked and cleaned grounds
• Four hole neon injectors
• NGK plugs
• Coil rail
• Oil filler cap
• Fuel filler cap
• Drained and cleaned fuel tank
• New fuel pump (fuel pressure heaps better)
• Purged the fuel line
• Seafoam & Nulon upper engine cleaner
• Reset the ECU (a number of times)

Oh, replaced the head liner while I had the car sat in the backyard.
