Thank you all for your advice, it is a AWD with no selection switch for 4×4 or rear wheel drive, I have noticed that the tires are not the same so I will have to take care of that problem first, thank you all once again and I will keep you informed

i wish there was a way to send the picture i took of it, as it would be able to give a clear picture of the damage, where the crack is was not cause by off road driving (just to and from work), but by RUST

hello everyone, i have a question for this forum, i have a 99 Jeep Grand Cherokee and found out that my chassis has cracked at the rear , were the lower suspension arm attaches to the chassis, my question is, is this a common thing and if so is there a way that it can be repaired SAFELY, or is it quitting time

I would start with checking your fuel pressure, both in KOEF and KOEO, also if you have a scanner look at the fuel trim spec (ltft), Let us know the results.

based on all the information given so far the only thing that may shed some light would be the the long term fuel trim infornation. see if you can get that and let us know what the results is

Try checking your fuel line pressure, if it is low it can cause the engine to misfire

After you crank the engine, remove one of the spark plugs and see if they are wet from gas being sprayed into the cylinder, if dry check your injectors.
