charlierh2 Posted May 20, 2004 Share Posted May 20, 2004 97 Legacy Lsi 2.5l auto On very humid days ( like after a warm night when it rains) the car runs very rough for a little while. The first time this happened I had the wires and plugs done. Now it just happened again and this time it kicked a CEL. At first it was flashing then it went steady then the next day it turned off. Other than going in and getting it pulled what could cause this problem. And what does a flashing CEL means vs. a steady one? thanx very much Quote Link to comment Share on other sites More sharing options...
applegump Posted May 20, 2004 Share Posted May 20, 2004 I used to have a similar problem. I had success with injector cleaner (stuff you put in gas). Id try that, very cheap fix. Quote Link to comment Share on other sites More sharing options...
blitz Posted May 20, 2004 Share Posted May 20, 2004 I'm thinking you might want to start it up on one of those humid mornings early (before the sum comes up) and have a look under the hood to check for visible arcing or coronas on any of the ignition secondary components including the coil pack. Sometimes you can hear the snapping noise of an arcing problem. The flashing CEL means that the ECU is logging a code that is read-able for information as to where to begin searching for the problem.
