The ECM is functioning but the problem is the way the data is being communicated to the scanner. There are several different procedures to follow when reading scanners so ensure that your connecting cables are right for you ECM and scanner.

if throttle blades dont move look on side of carb were kick down cable was replaced possible throttle and kick down popped off or damaged

Carter AFB or Edlebrock

Disconnect hoses at firewall and run high water pressure thru hoses.

maybe you should have the battery cheked and all the cables and the soliodes

Check the middle wire on your distributor. It's the ground for the coil. Granted you have an HEI distributor. If all the wires seem to be just fine, take the ignition module off and take it to your local NAPA. They have a load tester that tests those ignition modules. Have them test it several times. It may test fine the first 2 times, then on the third test, it might fail. It sounds like the module quit working like it should.

Check for ATF leak first. It can be on the high side of the pressure line. Example At radiator or along the line. Check ATF after 5 minutes of warm up time. ===== Check your service record for past filter/atf change. The recommended interval is 24,0000 miles.

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.

Anti lock has nothing to do with it. the brakes operate without ABS. run the motor then turn it off. pull the vacume hose off the power booster and listen for a suction sound. if none. plug it back and start the car. pull the hose and put your thumb on it. it should ****. the booster depends on vacume to work. If you have vacume to the booster and the pedal is hard, change the booster.(scrap yard)

the firing order is stamped on the intake manifold.  next time replace them one at a time.

its on same circuit as dash lights

How old is this car ? 1988 time to retire it i think as it could end up costing you more to repair than its worth ,

that sounds like a loose wire in your switch, or a faulty light switch.

purpose of O2 sensor is to fine tune injection system by monitoring exhaust stream and know what is the amount of oxygen. then is rich or poor then modify injection rate duty cycle

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

no ,O2 sensor will go all the way up out of range and the car won't stall,you will have multiple code set in PCM.
