Have you checked the intake manifold bolts to see if they're loose? Ever spray carb cleaner around potential intake/vacuum leaks at idle? Check the ground at the MAP sensor specifically?

Not if it's opening from 1500 to 2000 RPM..................

If the PO used the wrong intake gasket, good chance there's a vacuum leak where the intake meets the head.

Remove and cap the vacuum hose to the EGR.

VERIFY the issue.

takes minutes to look. What plugs? What gaps?

Have you removed the distributor cap and inspected it inside? FWIW, new plugs, wires, cap and rotor at every 30,000 mile tuneup.

With it running, start wiggling wire harnesses.

See the post above from October 2013 by Eagle. Use this diagram for reference.

Fuel pump ballast resistor may be getting hot. Jump it.

Okay. How does the fluid look now? Does your Power/Comfort switch light up when switched to Power? Is the "trans" fuse in the fusebox good?

Push the button in and PULL the cable housing toward the valve cover.

TV cable takes 22 seconds to do.

adjust the cable ASAP

adjust your throttle valve cable. What's the fluid look like now?

Jump the two wires together eliminating the resistor and see what happens.

CRUISER'S MOSTLY RENIX TIPS RENIX VACUUM HARNESSES NOVEMBER 17, 2015 SALAD 23 COMMENTS EDIT The vacuum harness that attaches to the front of the valve cover and includes the grommet/fitting, and is called the front harness, is Napa part number BK 715-1367 or is a Dorman 46003. The vacuum harness that is closest to the air cleaner, EGR etc, and is called the rear harness, is Napa part number BK 715-1366 or is a Dorman 46004. The tube from the rear of the valve cover to the intake manifold is part number BK 715-1365 or Dorman 46005 and comes with the valve cover grommet. The Throttle Body to MAP hose is no longer available. Click HERE to access a fix for that.

They run great til they break without warning.

We can get the 4.0 running.......

Which lines?

Radiator can stay in. Here's a pic of a bad balancer. Before doing anything else, I'd squirt some silicone spray on the belt with the engine running and see what happens. Could just be a cheap belt.

TPS is for an auto trans. No worries. Do the CAD delete. Pull the fuel pump out. Check/replace the hose. Visit www.cruiser54.com and complete Tips 1 through 5. There's a bunch of other easy stuff to do on the site, but it can wait til the Jeep starts and runs.

Actually a 2.46 liter....... How old are the tires? It sat for a long time?
