It isn't a speed sensor. In 1989 all GM front drives were hydraulic shift. Do you know if it is a three speed or four speed. The speed sensor in 1989 only controls the speedometer. Also can you describe the problem. Does it just slip? Only certain gears?
Replace crank sensor in 89 olds cutlass calais
Scottykw I have an 88 Oldsmobile Cutlass Calais quad 4,2.3L needing help locating the knock sensor on my car,rough idling and slow and sluggish acceleration.ive replaced the crank shaft position sensor and spark plugs,and fuel filter and allot of other things, but not the knock sensor or the Mass air flow sensor...where can I locate the knock sensor?

You need to figure out what you are missing. What is the fuel pressure at the rail when you are cranking the engine? It needs to be above 40PSI. If you have sufficient fuel pressure you need to check for spark at the plugs while cranking. If you verify you have sufficient fuel and spark then you need to look to timing and compression. These are the four things an engine need to run. Fuel, spark, compression, and timing.

Change the fuel filter and if it continues then check fuel pressure at the shrader valve on the fuel rail. It also could be a bad low side coil. Is the check engine light on when it's running? Get the codes pulled.

FUEL PUMP.
Have you checked the fuel flow and pressure?
If the fuel pump is over 160,000kms/100,000miles it's done.
Put in a complete assembly,if your mileage is close to above numbers you need a new pump anyway and it may (90% chance) will cure your rough running engine.The other 10 % is contaminated fuel and electrical, but as you have no codes I'll say FUEL PUMP.

Your problem might have it's root in electronic sensors but historically a fluctuating idle is associated with fairly tangible things - intake air leaks and/or inefficient fuelling - worn or dirty carburettor, bad injector spray patterns, worn throttle shaft and suchlike...
A splutter on sudden acceleration can have similar causes or be rooted in worn or wrongly gapped spark plugs or simply not enough spark power.
It is true the three items you mention are associated with fuelling but I am against replacing stuff unless it is known to need replacing and before looking for electronic cures it is important to go back to basics and check the engine condition and any adjustments or replacements needed.
If the injector spray patterns are bad or if the intake valve seats are imperfect or the fuel pressure regulator isn't working the exhaust gas will be giving the wrong story to the oxygen sensor which in turn will be sending the wrong signals to the management computer. The computer in it's turn tries to weaken the air/fuel ratio when it should be doing the reverse or vice-versa. In most cases it pays to do the basics first...
How to remove heater core
You have to pull the instrument panel , then the heater box . Lot of work, you can find videos on youtube showing step by step how to do it.
89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed
This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.These can be if the vehicle has them cleaned using a special zero residue spray cleaner.First have it scanned to see what if any errors it shows--the computer.
