Service Engine Soon light on Oldsmobile 1988 Delta 88 Royale

The light is on because the EPA requires car makers to have the computer run checks on various pollution control systems on the car while you drive and turn the light on if anything does not pass the self test.

It could be something as simple as a loose gas cap or a bad gasket on the gas cap (due to age, not miles on the car) that is turning the light on. You are right, this will not affect how the car runs, but it will fail the pollution control test.

Yes, disconnecting the battery for about 20 minutes should turn the light out. But you won't know what the problem is. Try to get an auto parts store, like Auto Zone, to "read the codes for you" and see what the problem is. They should do this for you for free. If not, go to another auto parts store.

Once you know the reason for the light being on, you can decide what to do next.

Car will start and run until it reaches operating temp. Then it dies and will not start for several mins. 1988 Royal 88 3800

MAF sensor is located between air filter and trottle body. During warm up take a screwdriver and lightly hit the MAF sensor if engine stall. then you have MAF sensor defect.
other thing is crankshaft sensor behing the harmonic balancer could touch metal when engine is hot enough have a look then good luck

My 1989 oldsmobile 88 royale wont start just pops and back fires there is normal spark and injectors are pulsing, there is correct fuel pressure and everything crank sensor if fine, could it be the cars...

It's under a cover (on the order of 6' wide x 12" high) on the top front face of the engine. It's quite a job to remove this cover. A less laborious method to determine if belt is broken is to run a compression test on the cylinders.

You may get someone to come to the vehicle to do this, else it'll have to be towed (unless you have the equipment to do it yourself).
But you can't use the car in its current condition, so maybe towing to a garage is a reasonable option...?
