i have a 96 that through a check engine light the other night and the two scanners i used will not read the codes. All the fuses are good and i checked for continuity from the data link connector and the pcm and all are good. when i originally bought the trk it would not scan then either and i forgot about it. well now it through a light and runs like crap intermittently and i cant read it. What do you guys think? Thanks
