Question about 1999 Jeep Cherokee

1 Answer

I have a 1999 jeep cherokee sport with a slant 6cy 4.0L that is hesitating while you are driving. When you are stopped and in park it tries to stall on me. I took it to Auto Zone and the codes came up to the o2 sensonrs, upstream and down, we replaced them and the map sensor and did a tune up, no change. Now the engine seems to be taking in more air. Any ideas on how to fix this problem?

    I was also told to check the fuel pump. We rebuilt the motor about four years ago. All new pistons and we had the head re-machined. It's turning into a money pit

Jeep stalls


try doing the procedure below, should cure the problem.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
