My Eg won't start nomore it ran and then shutdown with the oil light blinking.. Checked my oil and its good... On level... Sometimes it will start but wont run good... Code 48 came up for obd1.. Dnt know if that's the cause

 

For the oil light, it could be many things keeping your engine from building and/or maintaining oil pressure. If you think your mechanically inclined enough (i don't know if you are or aren't) to take off the oil pan and check your oil pump and all the gaskets included in it. May not be worth it due to this not being a one day kind of project. Up to you really
For the code, check your vacuum lines, your fuel filter, and your fuel pump. These can all cause a code 48.

 

Code 48 is an oxygen sensor issue, if I remember correctly. Not sure you are on the same page here.

 

Blinking oil light means a tempory drop in oil pressure,and will blink until the key is turned off then back on, oil light on steady means low or no oil pressure
