I have a 97 rdstr. Earlier the check left engine bank light came on. No loss of power or other noticeable drivability issues. I turned car off anyway, resterted check engine was normal(went off as the car did the systems check) BUT..... went on about 30 minutes of driving later again with no drivability issues. I came home;any thoughts????

Bummer. Not to brush it off, but there are a lot of post's on this subject. Do a search. First you'll have to do the on/off key thing to find how many flashes. That will narrow the problems.

I bet it is either the O2 sensor or air sensor. Hope this helps

Thank you both Raymondo.and 215mph. I did the key on/off. No flashes but the low oil pressure symbol stayed on both times I tried it. Oil level is good (a little overfilled maybe). As I was driving I always check oil pressure,temps etc. nothing seemed out of whack,

I agree it could be the O2 sensor

It seems very odd that the engine light would light up and not give you a code. Turn the key on-off-on (but not starting the car) and wait for the offending light to flash. Count the times it flashes and you will have a direction where to start.
Is the low oil pressure light on while the engine is running? What is the status of the oil pressure GAUGE while the engine is running?

Thanks everyone for the thoughts. Sorry about delay in answering;(was busy with delivery of my Murcie.) The low oil light is not on when driving; the oil gauge reading is normal.
