oil light on 1998 toyota camry keeps blinking off and on

I think you have two separate issues here. First, have someone put an oil pressure gauge on and make sure that you have the correct oil pressure. That will tell you if you have a bad oil pump or pressure regulator. The dying goes, you may just have an old weak battery. Or your alternator may be bad which will also cause the car to die once the battery has lost it's charge. I noticed that this is an older post. Have you made any progress?

Speed sensor needs replaced on compressor Bottom of compressor replace 134 Aswell

batt is new, oil light comes on as blink, rev up engine and it goes out stops blinking, happens when engine temp is normal no problem when cold /
