Check Engine Light

My check engine light just came on this AM for no apparent reason on my 2004 Jeep Grand Cherokee. It's the coldest day of the season so far so I'm thinking that may be it but I'm not sure. Any thoughts or reasons would be greatly appreciated!!

Actually, just go to your local auto parts store and check the codes for free. If you go to a dealer, look forward to shelling out a minimum of $75 dollars. Most of the time its a oxygen sensor or something like that.

It could be one of a hundred reasons and maybe nothing serious. I suggest getting it to a Jeep dealer where they have a list of all the VAG codes from your particular engine.

The check engine light is a general warning that you have a problem that needs attention. Diagnosis of the problem requires a computer scan. You can have this done at most auto shops and parts stores, and many will run the scan at no cost to you. Your transmission problem may be the cause of the light, but even if it's not, the scan may give you some insight into it as well.

2004 jeep grand cherokee 6cyl. check engine light comes on occasionly and stays on till car is shut off, then it may or may not come on the next time you start it Thanks Bob

You need to have somebody pull the code from the system while the light is on. Most local parts stores will do this for free. Once you get the code it will give you a direction as to what is going on with your truck. Computers can set codes for 1000's of reasons, and without knowing the code you have no idea what problems it is seeing.

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.
