Question about 2002 Jeep Grand Cherokee

1 Answer

I have a 2002 grand cherokee. Was on my driveway backing up (on a incline ) when all of a sudden engine light came on and started running very rough with loss of power. Shut it off then restarted and took around the block tosee if it would correct itself. No such luck.

Your PCM (engine computer) senses a fault code with an engine management component. You will need a codes reader to retrieve the code. If you you do not have a code reader, go to a well supplied auto supply store like autozone, and they will read the codes and let you know what they are. This would be the first step any Tech would do before diagnostic testing begins.

    Guess what i've got the answer. A 2002 grand cherokee will not show a bad CAMSHAFT SENSOR in a scanner, it will only show the crankshaft sensor. Yet a lousy $25.00 or so later it's done. Replace your Camshaft sensor, make shure is OEM original no cheap ones.

98 jeep cherokee sport flashing engine light


The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

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.

Grand cherokee laredo 95 4.0 liter. motor run rough.need the timer orhow to fix this


These vehicles are timed by computer. You should start by pulling the engine codes, and then checking the systems that the codes reference. there are many many things that can make an engine run rough. I, in particular, think this is typically a wonderful engine. If you are competent, start with the basics...usually both the simplest and least expensive...look at the tune up items if they have not been done recently...but again, first start by pulling the codes if there are any present...meaning the check engine light is on. Post back what you discover please.

2002 jeep grand cherokee with 4.0 engine will die but restart


I do not know what the error codes mean but know that When I has the sme problem with my jeep it was the fuel pump. What happens is when it heats up it es less and less fuel and chokes the engine. When cold it runs better. remember gas in the tank helps cool the pump but sounds like your pump needs replacing as it is starting to give out.
