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.

SOURCE: Jeep Grand Cherokee Service engine light soon on

A loose gas cap will sometimes trigger the service light to come on.  Since this appears to have happened on multiple occasions I can assume that this is not the problem but may be associated with it.  The level of gas in the tank affects the amount of atmospheric pressure in the tank. There are multiple things that could set off the light, one being a loose or defective gas cap, and the other is a fuel vapor return valve.  I'm not sure of the exact type of fuel system you have so I cant give a more exact answer.  If you wanted to give something a shot before bringing it into the shop, you can simply replace the gas cap first, a very cheap try.

SOURCE: 1997 jeep grand Cherokee laredo hesitation problem

You should add a rs4 performance chip or the fuel economy chip also made by rs4. there like 70 bucks. If the problem is electrical changing your chip could solve the problem. Even if is doesnt work the chip will make your truck idle more smoothly, have better throttle response, and you will add 3-7 mpg. I bought one for my 1997 jeep grand cherokee straight six, and it felt like i was driving a different truck . It mae that much of a difference...you cant loose!!!Like everyone says , it could be a vac leak or a clogged fuel filter , soetimes bad gas...your problem is a needle in haystack. Try the chip...I hope this helps

Check the fuel pressure. If you have 30K miles on your jeep and the spark plugs in this motor need to be replaced. Jeep Grand Cherokees are notorious for not doing well with fuel with lower octane. Fill your Jeep with at least medium grade gasoline, especially if it has been shuddering or hesitating while you're attempting to accelerate.

Hesitation when accelerating, mostly between 20-30mph,


the funny thing is , we have had this problem also , the check engine lite came on , said downstream 02 sensor bad. replaced it. still had hesitation. change plugs and wires. still had hesitation, replaced fuel pump/fuel filter/fuel screen assembly, and the S.O.B. still has this problem. im running out of ideas except that i have run into other posts that say the crank position sensor , or the computer itself could be the culprit... all my switches and and other components seem to be working fine, though it makes me wonder also if tha cam sensor could also be going bad....
