i was crusing this afternoon.. 4th gear, vac->1 psi or so.... all of a sudden my CEL came on, so i let off and got ready to pull over. engine made no verbal or feelings of somethign wrong. When i clutched in, it went off.. so i just kept going. it didn't do it again for the rest of my 15 min drive back to my house. any ideas if A) its still in the ecu to pull it (if the code cleared itself, will it be pull-able?) or B) what it might be? don't say the map sensor, cuz i have a 3-bar. don't say a bad check valve cuz i have hondata/boost that can read up to 27 psi. im sure it can handel 1. since it didn't make any sputtering, backfiring or hesitation at all, im guessing its not related to fuel or spark delivery... other than that, i don't know where to even look.
