Well - it sounds more like fuel or vacuum because while it may seem to be 'running great' at high RPM's - it could just be leaning out enough to carry the mixture. But either will often trip a CEL (fuel less so because it tries to compensate for fuel octane first). Have you checked your ERG valve between the manifold and the cam cover as well as the airmass sensor array? Get a fuel pressure reading too, it could simply be a filter or regulator. After that - it migh be that you have a wrong/bad ignition CPU. 1993 is a weird year. -- Radio Free Dexterdyne Top Tune o'be-do-da-day Mr Ray Charles - I'm Busted http://www.dexterdyne.org/888/184.RAM all tunes - no cookies no subscription no weather no ads no news no phone in no sign up required - all the Time
