Won't Idle Correctly After Attempted Repair-What Next
I have a 2000 Jeep Cherokee 4.0L ( XJ ) limited trim. It will not idle correctly. below the regular RPM or above..... i replaced the idle position sensor and had the IAC system reset by a friend who is a mechanic. ( idle sensor was to blame, to keep my question short). Everything seemed to be quite fine having done this yesterday. Even seemed to run better/stronger.
Until this mourning when it would not idle at all.... until i started and held the gas down above idle speed for about 60seconds. Also does not idle at a consistent speed and occasionally idles rough.
I will be doing a tune up over the weekend since it is due, which is fairly easy with no plug wires etc just the ignition pack over the plugs.
I am not sure if this will help with my current problem since the computer should correct within reason for any ignition timing if i had bad plugs? yea?
If anyone has any ideas? let me know. If i had a bad part in the ignition system it would throw a code? and the check engine light has yet to come on and everything checked out ok just yesterday.
