Is there an actual question here? If so, then get the codes pulled and go from there. Speculation = :thumbsdown

You could disconnect the SAFC and fill up with regular gas to see if the problem goes away. Not sure how the O2 sensor deals with E85, since it didn't exist back when the car was new. :shrug

Most likely with running E85 your car thinks it has fuel vapor leak because E85 doesn't produce the same pressure in vapor form. the big ass post I made about E85 has the full explanation in there somewhere

96's are notorious for throwing a MAP code with an SAFC. if you're getting an air memter related code, it's the SAFC that's causing it.
