Well, the problem still exists but I'm thinking it's electrical. Last week it ran with no problems. I ran the gas all the way down and then filled it back up. The past two days I've had a little trouble. Once again, it seems to be more geared at lower rpm's and not dependant upon how much fuel I have. I'm starting to wonder if it's my Apexi S-AFC. I've checked and rechecked the ignition componets and even the O2's, everything seem okay. I know there's a "sensor check" mode on the S-AFC, I just have to have it turned on and hope it fails to see if the module isn't communicating properly (ie: fails to detect a sensor, they work fine when it's at idle).
If the module checks out okay, anything else I should look at? I just wish the damned thing would throw out a CEL or for the problem to be consistant.
Thanks!
