few problems with my cherokee
ok first off i am new to jeeps, mostly had chevy sport cars (camaros monte carlos etc) all my life. so hello to everyone as this is my first post.
so i just bought a used 2004 jeep grand cherokee over land edition. i love the thing but i am having a few problems with it.
Problem #1. standard cruise control problem, will turn on but not engage. did some searching online and looks like the most common problem was a vacuum leak. i read that air will only blow through the defroster only and your cruise control light will say it is on but when you set it, it wont engage. but now with my jeep. i do get air through the floor to the defrost and my cruise control light will come on but will not set. i have checked all the fuses and they are all good and checked the vacuum lines and they appear to all be good as well but you never know, so i will have to check those more thoroughly when i have time. as i am moving to new orleans very soon i would love to have the cruise control working on the long drive.... so if anyone can help me with this problem i would be in your debt
problem #2. knock sensors are acting up and says i have an fuel leak (got the codes from turning on and off the key 3 times). now the check engine light came on one time after i gassed up not to long ago and i figure it was because i did not put the gas cap back on properly. but i have tightened the cap and put it on right but the check engine light is still on. is there a way to reset the codes? and i read online the knock sensor codes will come up if i am not using the correct gas (which yes i have been using the cheaper gas). the exact codes are P0325, P0330, and P0442
thanks in advance
