Question about 1999 Jeep Wrangler

1 Answer

1999 wrangler problem: high idle,and hesitant.

Last month my jeep was giving me problems with a high idle about 50% of the time when in park or neutral and then the check engine light came on and when driving any time I would have to go up a hill or have to increase my rpm's i would get a hesitation as if i was letting off the gas and hitting it real quick. I took it to auto zone they said it was the tps. I took it to a mechanic he said it was loose and he tightened it. Im now getting the same troubles again. Does that sound like the tps or something more?

If it was originally scanned by auto zone and they said Throttle Position Sensor (TPS),i would go back and have it scanned again,this will tell you for certain what it is.Try and get the code number and definition written down.If it were TPS again,the sensor itself would need to be replaced unless the cost was prohibitive,or the wires to and from the sensor and PCM (vehicle computer),ohms checked for continuity first.Eliminating the wires leaves 2 entities in the circuit,the PCM or the TPS.Checking circuits is costly in labor dollars.Good luck.

Hesitation is usually a dirty throttle body and idle air control motor.

Will idle high sometimes up to 3000 rpms when driving or sitting still


I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.

95 jeep wrangler overheating and hissing sound


Had the same problem on my 95 Wrangler within the last month. I was told that the radiators on Wranglers tend to wear out, and don't push fluid through after 10 years or so. I decided to 'fix' everything at the same time. I replaced the radiator, the radiator hoses, and the water pump. That stopped the leaking, and fixed the problem. Water pumps run less than $50, and is actually something you can do yourself. I'm not mechanically inclined, but I needed to save the labor charges from the mechanic, so I took at shot. I had no problems. It does help to have an extra pair of hands to replace the serpentine belt.

99 jeep wrangler 4.0 backfires and hesitates


Fairly common problem. Typical scenario is start vehicle, runs fine for 15 to 30 seconds and begins to backfire when placed under load as customer tries to drive vehicle. Flooring usually makes the problem go away. Usually does not throw a code.

Fix is to replace the upstream 02 sensor.

Acceleration hesitation


Depends how long since your last tune up and mileage. I would do a normal oil change, oil filter, air filter and plugs. If she still does it, try checking for a vacuum leak. Start the vehicle and spray "lightly" carb cleaner around your vacuum lines. If you have a leak the engine will increase in idle suddenly. Replace the line or part. AS A LAST resort and pretty rare is the distibutor. They usually run about 75.00 to 110.00...hope this helps.
