1990 olds 88- the service engine soon light is always on

This car probably doesn't have a obd2 connector. More and likely it is the obd1 which most car part stores wont check. find someone that knows how to take a paperclip to access codes from the service engine soon light. If the light is staying on your "brainbox" sees that one of the sensors is not working to the cars standard. They make a obd1 connector that will plug in and will do the same thing.

What is the code 22 in my 1990 eighty eight olds

Code 22 is a Throttle Position trouble code.
Either the throttle position is not returning to home position, or more than likely the Throttle Position Sensor (TPS) is worn.

The throttle is at two positions most of the time. Either completely closed (not driven) or slightly open while driving. The slide wire will eventually become worn and give faulty readings to the computer, eventually causing the fault code.

The sensor is easy to replace and costs about $45.00 at Autozone or O'Reilly's.

Please let me know how I may assist further

1990 olds 88 door unlocking problems inside and out

Remove the door panel and check the linkages for the locks. Sometimes with age these begin to warp and no longer work as good. I have a 91 S-10 and recently had to replace all 4 linkages for my locks and door handles.
