the code is for mass air flow sensor maf not sure if its the same as map sensor on your car but it should be near the air filter check the wires make sure they aren't broken or exposed and if not changing the sensor should help and leaking fuel isnt good id fix that first because it could be allowing air in there that could throw off the sensor you can try flexseal tape or something similar or a strong jb weld might work as a simple solution or just cut the pipe and add a couple of connectors on each side with a piece of the pipe in between them to actually fix it without replacing the whole line once its fixed check to see if problem is fixed if not try the sensor

fix the fuel leak first you can try a flex seal tape or a jb weld make sure its dry when you do it. thats a cheap fix to see if the air gets 8n there throwing off the sensor. the better option as an actual repair is to cut both sides of the leak remove the broken piece use two connectors and a piece of fuel line to fill the gap between them. if the problem still exists move on to the maf sensor should be on the air filter box area check the wires snd plugs make sure connected properly and no broken wires then change the sensor if still not fixed

Hello there!
Sounds like you've done a lot of troubleshooting already! Let's break down the issue and see where we can go from here.
The P0102 code points to a mass airflow sensor (MAF) issue. Even though you've replaced the MAP sensor, it's possible the MAF might still be acting up.
The fuel leak is definitely a concern. It could be causing fuel pressure issues, which would affect the engine's performance.
The stumbling and misfires at 3500-3800 RPM suggest a problem with the ignition system or fuel delivery.
Here are a few things to check:
1.) Fuel Pressure: Ensure the fuel pressure is within the manufacturer's specifications. A fuel pressure tester can help with this.
2.) Spark Plugs and Wires: Inspect the spark plugs for wear or fouling. Replace them if necessary. Check the spark plug wires for cracks or damage.
3.) Fuel Injectors: Test the fuel injectors for proper operation. A fuel injector cleaning or replacement might be needed. Ignition Coil: Inspect the ignition coil for signs of damage or failure.
4.) Ignition Coil: Inspect the ignition coil for signs of damage or failure.
If you've already checked these components and the issue persists, it might be worth consulting with a professional mechanic to get a more in-depth diagnosis. They can use specialized tools and equipment to pinpoint the root cause of the problem.
Once you've identified which part needs to be replaced, click this link to be directed to our website where your vehicle information has already been entered. Simply enter the part's name into the search field to get started.
Fingers crossed it's a quick fix and you'll have your LeSabre purring like a kitten again! Good luck!
