Hello Everyone,

Just picked up the Donor for my 2WD and before doing the swap I wanted to test the tranny and TC.

The problem is the XJ won't stay on. It will start (after more than normal cranking time) and idle very low. As soon as I put it in gear and slightly press on the gas it dies.

I read through the idle problem threads but didn't see one that would die when pressing the gas pedal.

Thanks for the Help.

 

Forgot to point out some details...

The Xj has been sitting for at least 2 years. Its a 1993 4D 4WD Auto 170k

 

Anyone?

 

Have you put fresh fuel in it?

 

You could try Seafoam...Slowly run about half a can through the vacuum line from the brake booster and shut it off for an hour to let it soak and soften up any gunk in the fuel system. Pour the rest of the can into your gas tank. When you start up the engine again you are going to smoke out the whole neighborhood so be prepared. The smoke is normal, it's the gunk burning out of the system. Just let it run till the smoke stops.
Hope this helps...

 

As above. Try fresh petrol

 

Drain the tank completely first. The gas in the donor Jeep went bad after about 3-4 months of sitting.

What you've got now is sludge and varnish with little to no octane. All the good stuff is gone.

I ran into a problem like this a few years back, it seemed to run fine, a little on the low side but the second you put it in gear it just quit. It wound up being a loose wire on a sensor hooked up to the Transmission. For the life of me I cannot remember the sensor name and have begun looking it up for you. It has to do with the idle control in the transmission though, I would suggest start looking into that. It took me a week before I could finally figure it out.

 

Well we got a little inpatient and since I really only need the 4x4 parts we moved/lifted the XJ the easy way.
