Question edited for clarity. Question moved to model category. That is proprietary information that will not be available to the general public as no one is supposed to be inside them. If you are, they all have a number on them and that is the electronic part number. The best plan is to send it to a company that repairs ECMs. As you can see, no information online. https://www.google.com/search?q=1995+Cadillac+Eldorado+ECM+Mosfets ECM repair - exchange - replacement https://www.google.com/search?q=1995+Cadillac+Eldorado+ECM+repair ..

Those are mem-cal codes, unless you changed the ECM the PROM (a separate part inside the ECM) has gone bad or the ECM itself went bad, if you just replaced your ECM with a used one you need to swap PROMS just remove the 2 screws and remove the plate then the PROMS. If this doesn't workYour best avenue is to remove the ECM then go to a parts store that sell Standard Motor Products they have an R+R program and will repair your ECM and PROM and send it back. I hope this helps. Take Care.

DTC P0452 Fuel Tank Pressure Sensor Circuit Low Voltage The fuel tank pressure sensor is located on top of the fuel tank. Circuit Description The fuel tank pressure sensor measures the pressure (or vacuum) in the fuel tank. The powertrain control module (PCM) provides the sensor with a reference voltage, a signal circuit, and a ground. The sensor returns a signal voltage to the PCM relative to the pressure in the fuel tank. The PCM should see a signal voltage increase as the pressure in the tank decreases (more vacuum). As the pressure in the tank increases (less vacuum), the PCM should see a signal voltage decrease. The PCM uses the sensor signal to test the integrity of the EVAP system. If the PCM detects a signal voltage that is too low, DTC P0452 will set. Your best bet , take your vehicle to a qualified repair shop.

Are you sure it is not an electrical problem? Spray some starting fluid into the throttle body. If it starts, then it is a fuel problem. If not then you need to look at computer or sensor problems.

You will need a steering wheel puller. You can borrow one from most auto parts stores. You will need to remove the horn airbag center to expose the bolt. Loosen the main steering wheel bolt till it's almost off then attach the puller. Keep tightening the puller till the steering wheel comes free.

You have to remove intake manifold and you will see it,yes I know it does not seem right but it's there

Surging idle is almost always caused by a vacuum leak, not an electrical issue.
