2002 Jeep Grand Cherokee-runs rough and pops back through intake

Posted by on

  • mechanic144 May 11, 2010

    it sounds as if a good tune up is in order here...use the factory spark plug and change the fuel filter and air filter....this should get rid of the popping sound through the intake as well..this could also be a result of pre-ignition or detonation...try a tune up first....and a fuel system service at the dealership....

Why dose my 2000 jeep cherokee have a rough idle but seems to run good at freeway crusing speed just bought the vehicle last owner thinks it has a low cylinder compression


My wife's 2004 Jeep Grand Cherokee has had the same problem what I did was take the air intake tube off and cleaned the carbon build up around the air intake valve. I used carbrator spray and a soft cloth to clean this build up off. Make sure to change your air filter and clean out any debris in the air filter box and other air intake tube. If this doesn't help check the Jeep website for information about some electrical module that when it's bad can causes this problem.

My 1997 Jeep grand cherokee is running real rough when I accelerate. Now while driving it it keeps stopping but will start right back up? help???


check the cables of the spark plugs, some times it occurs that the cables get loose from its plastic retainers and touch any metal in the engine, causing missfire of the related spark plug, hence rough running of the engine. Put all cables on the retainers making sure none touches the bare metal of the engine. That should help.

2004 Jeep Grand Cherokee (63,000 mi - V8) Check engine light indicates #1 cylinder misfiring. Spent $$ getting system flushed for carbon residue. Drove 3 weeks, started up, ran rough, and light came on...


The miss,does not just come and go,if it is a engine valve,replace the coil and boot,go from there,if this does not solve the problem,then the injector is gone out,or going out.If it is a engine valve,the miss would never get better,then worse,it would be the same all the time,get him to run a air compression test,get the valves up(close)and see if any air is detected threw the exhaust,or the intake,it will be present if the valve is the problem.

2005 jeep grand cherokee limited 5.7 hemi vehicles hesitates


The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.
