IN Car trouble

I have a 1989 Mazda RX-7 convertible, it chokes out
when I drive it on the road, the engine light comes on and
then it runs awful

Pull the trouble codes. I'm betting the metering oil pump has failed and the car has defaulted to limp mode.

since It is an S5,NO..you cannot Disconnect the Oil Metering Pump.
It NEEDS to be connected and the ECU needs to SEE it Connected,(EVEN IF you decide to Premix.If you decide to Premix you have to Take the OMP out and Dangle it Somewhere in the engine bay..That or Go Standalone Computer.)
you need to find a GOOD OMP...Post a Wanting to BUY in the Sec Gen FOR sale Section and also the "regional" For Sale sections of the Forum,Someone May have one.and it wil save you from Buying from the "stealership"..Good Luck.,sTYX.

Not sure what this has to do with jack stands, but OK.

An ODB1 scanner won't help you.

No. The ECU must see a functional metering oil pump or it will go into limp mode.

A failed OMP on a S5 will more than likely take the ecu with it
