Imma CJ Guy--These computer rigs are not my cup of tea.
I noticed you had been waiting a while for an answer.
I will throw SOMETHING AT YOU. May help--May not. But I try!
1st and foremost, if your check engine light is on. Get it CODED!
This can be done at most Popular Auto Parts Stores. FOR FREE!
Return here with the codes (regardless, we want to know too!) Many times the auto parts store may can DEFINE the CODES, and possibly tell you what to do to fix Him (a pronoun used for a "Manly" vehicle, not a "Sissy" one!)
While you are there, have your battery and alternator tested.
Lastly, DO NOT DO THIS UNTIL YOUR CODES HAVE BEEN RETRIEVED, or you will wipe them out!
Sometimes a Low Battery/ Alternator issue will make your computer go WILD. Jumping and charging "DOES" charge the battery, BUT does not help the "Hay-Wire" Computer.
From my limited COMPUTER understanding, and this has worked on some vehicles (cannot really hurt nuthin', BE JUST LIKE REPLACING THE BATTERY)
After the Coding, COMPLETELY DISCONNECT THE BATTERY,
Allow it to sit for 10 or so minutes.
THIS "SUPPOSEDLY" WILL RESET THE COMPUTER (BEFORE IT WAS STILL TRYING TO "HANG ON" TO THE BAD INPUT, FROM THE LOW VOLTS).
FULLY CHARGE OR REPLACE THE BATTERY, WHILE DISCONNECTED.
THEN HOOK BACK UP THE FULLY CHARGED BATTERY.
NOW BE SURE TO RETURN AND PAT ME ON THE BACK OR FUSS AT ME! I seldom get replies for my hunting and pecking, unless I'm in the CJ forums, then I'm in Hawg-Heaven! (This is my Hobby, just trying to help, not for the $$$)
LET ME KNOW HOW YOU FARE.
Someone here will help you, if I cannot. Just give us MEGA DETAILED INFO.
MY 2 Jeeps, at present, TAKE CARE OF 'EM, THEY TAKE CARE OF YOU!
