check engine light saved codes....lights go:

flash flash-flash-flash (pause)
flash flash-flash-flash-flash-flash-flash-flash

what does this mean?

 

Error code 48, if your count is right I'm at work so I don't know what it means, maybe somebody could help, if not I'll reply once I get home!

 

I see 13 and 17(two codes) or 48(1 code). Since 48 is not in my '91 FSM, I believe that these two separate codes are the o2 sensor and pressure sensor. Check all vacuum & electrical lines to pressure sensor. Replace o2 sensor if old. And, possibly replace pressure sensor if error returns after ECU reset after o2 sensor replacement.

Please elaborate: year/model/ long or short flash count as it continually repeats........
