Apply vacume to the vacume advance at the distributor.the diaphragm may not be working.also check to make sure the advance mechanism in the distributor is not siezed.the last thing you will have to check is when and if you vacuum ot the port on the carb that the hose connects to and at the correct time(throttle position)

AMC invented the first Cherokee and no GC EVER.

read the wiki on GC (quote)
The Grand Cherokee's origins date back to 1983 when American Motors Corporation (AMC) was designing a successor to the smaller Jeep Cherokee (XJ).[3] Three outside (non-AMC) designers-Larry Shinoda, Adam Clenet, and Giorgetto Giugiaro-were also under contract with AMC to create and build a clay model of the Cherokee XJ

Vacuum leak sort of sound coming from the general area of the vacuum booster on my 1981 Ford F-150 w/ 300"six cylinder and 4sp. It stops when I apply the brakes fully.


check the hose and the rubber around the vacuum booster the best way i found a leak was to
take a 3ft peace of fuel line and put 1 end up to my ear and take the other end and probe
around the motor or ware ever i could here a vacuum leak you don't have to use fuel line any hose will do

i hope this helps you

Took to inspection code p0171


engine running lean. Usually caused by vacuum leak. If you have a V engine, the failure is usually intake manifold gaskets. If you have inline (4-cylinder), the cause may be intake gaskets or bad or unhooked vacuum hoses attached to the intake manifold. Check all vacuum hoses for cracks or loose connections. Replace any suspect hose. To find manifold gasket leaks, spray ether or carb cleaner on the gaskets with the engine running. If the engine revs at all, you have a leaky gasket and must remove the manifold to replace. Please let me know if you have any more questions.

Slight popping back thru the carb at high RPM. Timing is set correctly


There is recorded case of oil soaking thought bottom of the distributor.
Open the cap and look the any sign of oil from the o-ring seal.
== Do not rule out vacuum advance line/hose. ==
Do a short test ran without air filter to rule out air restriction.
Add injector clean to rule out bad fuel. I recommend Lucas fuel additive. 3768a4b.jpg

My 1995 4.0L YJ has a miss while idling and hesitation while driving. I have checked the fuel pressure, 50 PSI, however when I removed the vacuum line from the fuel pressure regulator it did not fluctuate...


If the fuel pressure does not change when you disconnect the vacuum hose on the regulator, change the regulator (There is vacuum at the hose, correct?) Also, check the return line for kinks and internal obstructions.

It is possible that you do have bad rings and is causing an excess amount of crankcase pressure. Since you just have a hose hooked up now. Try running it to the big port vacuum fitting on the base of the carb.

It does sound like a vacuum leak. Get a can of WD-40 and start spraying around the carb. It will rev up, and U can pin point the loose vacuum hose, are crack vacuum hose.
