Hi im new on this so dont go hard on me lol
i got a cherokee 2006 with the engine 4.7 and i changed the sparks plugs i changed the egr valve also checked the catalyst converter with a thermal thermometer and one was bad and i replaced too also cleaned the tb now i dont know what to changed and the car symptoms are when its on parking and i press the gas to see the rpm and they normally go up without problem but as soonest i put it on drive and try to move the car moves but just feel sluggish and hard to move it takes some seconds to start getting the rpms up and if i turn the ac its almost impossible to move fast never gets up of 20 mph also when i press all the gas down to see if it works better it felt like doesn’t wanna change gear unless i let go the gas and press it again
kinda lost here and really need the car to go work thanks for your time

 

You have a Grand Cherokee. Not the same as a Cherokee.

Got it thanks

 

Updating.-
i call a guy who came and check the car with the snap on computer
and he saw 3 of my injectors where trowing alot of gas
so i took it out and i saw the little holes where the gas spray was just 2 big holes and my other injectors where 3 little holes change them and the car got alot better but still whenever it gets warmer it feels heavy but not as much as it used to another thing was i cant turn the ac on cuz the car just dies
also took out 3 of the spark plugs were i changed the injectors and they were all black and check the other ones and they look all right i clean the 3 sparks didn’t noticed any difference im thinking on buying some new ones and maybe changed the oil cuz i put some seafom on Saturday
also my rpms are going up and down not to much but u can noticed

 

Also reset the computer and drive it for like 20 min and got the code p0172 back again running rich bank 1

 

It's running rich?

 

Yes thats the code again and the bad injectors that i took out from bank 2 not 1
i just remember a detail maybe an important one it just feels heavy until you reach like 15mph maybe 10 it feels like it wants to die thats what i thing like it was needed more gas or air after that it gets like a normal car except that if i press to hard on the gas doesn’t shift of gear i need to let it go and press the gas right away and it shifts normally

 

You did the changing out of three two-holed fuel injectors yourself, on only the one bank? What brand did you replace them with? Are they a matching 3-hole set now to the other banks fuel injectors since replacing them?

I reccomend showing your Jeep more love than that.. I do not know how old, or worn out the other three injectors are in there right now? If they are not in very new-like condition to match its other bank? I think that they should probably be replaced now. Banks #1 and #2 are seperates. But, both of these banks contribute equally to do the work together.

Definitely put in new plugs. Grab two-and 1/2 sets, to be able to get the one bank twice, and for spares.

Definitely change the oil and filter. That is the most important thing.

Air filters are inexpensive enough to change it out if the one in there now is not in new-like condition.

Maybe check on the sparks a little more closely, by visually inspecting for having the appropriate level of sparks at the plugs would be a good thing to do.

If you know the Jeep, and can think of some things it probably should have done to it, that may contribute to this and other issues. Think of things that maybe need done, and get those done, if you are able?

 

Change oil and filter today and i just let it idle by the time that i got back my car was almost on red was overheating now
