94 ranger

Replaced the computer on mine, only 150.00 from NAPA and no more problem codes and running fine now. Hope this info helps you.
 
Hopefully that works I gotta get money first lol but it also has bout 210k on it n goin up cause its my dd n it burns oil too but you think it may be the computer then cause my check engine light comes on spiratically then it starts misfiring or something its really hard to hold 65 on the highway
