Why is my Jeep sputtering?

Posted on by Arif Clayton

Why is my Jeep sputtering?

A dirty or failing sensor puts too much or too little fuel into the engine causing it to run rough or sputter. If they are not working correctly or are dirty they don’t ignite the fuel cleanly and the car can misfire or sputter. The plugs will need to be replaced or cleaned.

Why does my Jeep Wrangler not accelerate when I push the gas?

If your Jeep Wrangler won’t accelerate, that is a serious cause for concern. There are a lot of different reasons that can cause this. Diagnosing the issue can be narrowed down by whether the engine is still revving when you push the gas or not. There is a section for each scenario with likely causes for each.

What is causing my Jeep to die ( stall ) at idle RPM’s, or up?

WHAT IS CAUSING MY JEEP TO DIE (STALL) AT IDLE RPM’S, OR UP… Hello and welcome to Just Answer. I am sorry to hear about your problems with this vehicle. If you like, we can try to do a few tests to isolate the cause of the problem. Your truck uses a device called an IAC valve to control idle speed.

Why is my Jeep Wrangler sputtering and losing acceleration?

I had about the same problem with my gals 93 Yj, it turned out to be a disconnected hose from the two roll over vent valves on the gas tank. If you take your gas cap off a few hours after driving and don’t get a hiss this could be your problem. Frank Could your fuel filter be bad? These voices in my head are giving me a headache….

Why does my Jeep Wrangler have bad valve springs?

The bad Valve springs, for example are only related to the older model TJ’s, which were synonymous for this for problem. Various codes should appear, some of which you can safely ignore, as well as a CHECK ENGINE light.

Why does my Jeep Wrangler idle all the time?

One more part that can cause a bad idle is the Throttle Position Sensor. My TPS went bad and my idle and acceleration became unbelievably erratic. Try cycling the TPS via the throttle linkage 40-50 times (without the engine running) to see if anything changes.

When does the Jeep Wrangler throttle position sensor fail?

It will start to do this when in gear running down the street and it is noticeable to the peddle. When you take your foot off the peddle the idle accelerates to 3000 rpm and you can’t shift…. I replaced the throttle positioning censor twice already, and it still does it.

Why does my Jeep Wrangler not start unless on the gas?

I already tried letting it re-learn it’s idle since the computer was reset. But she’ll crank and crank but won’t start unless I have the throttle wide open. Once she starts, she won’t idle on her own..I have to keep my foot on the gas. But this doesn’t happen every time, only when cold.

Can a bad throttle position sensor cause idle surging?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

Why does my Jeep Wrangler sputter when I accelerate?

Another tell-tale symptom is if the sputtering is in direct proportion to your RPM, i.e. the faster you drive the faster the sputtering. We are quick to assume it’s the injectors, however it’s very rare that Wranglers suffer from injector problems.

Why does my Jeep Wrangler make a bubbling sound when I hit the gas?

My Jeep sputters, loses accelation and makes a bubbling popping sound when I hit the gas (also my RPMs drop). Sometimes this is accompanied by my check engine light coming on. In the past year I have replaced my:

What is the problem with my Jeep Wrangler?

Cap, Rotor, plugs, crank sensor, fuel pump, thermostat, cat converter and transmission. For example, this was happening really bad on and off, then it stopped for a day or two, I then drove over 500 miles through the White Mountains with NO problem, I come home and now this problem is back again and even worse (again off and on but more frequent).

What should I do if my Jeep Wrangler is bogging?

If that don’t work pull the sensors and clean the carbon off them. A good mechanic should be able to tell you what sensor is causing the prob. My fuel is good.
