Check Engine Light on because of sensor(s)?

[Blue-By-U]

Ok, my CEI light is on and I don't know why. My 89 has 102,000 miles on her and I believe the O2's need replacing. Would replacing them solve the problem? They might be stock yes I know they should have been replaced at 80,000...they will be done shortly I just want that damn light off. I recently replaced was the TPS. Plugs and wires are also due.

Any insight will be appreciated.
Thanks!

There should be codes generated with that light. There are sites to assist you. Try EEC IV info at http://www.dalidesign.com and http://www.shotimes.com

Alex, anything we tell you without first knowing those codes would be a guess. Get those codes run and chances are we'll be able to tell you exactlywhat needsto be done to remedy the problem.
