It should only be one flasher. You do need to use the right bulb not something close. You could have a contact issue with the bulb or at a plug connection

If the battery was sitting that long, it cannot store much energy.

Probably the neutral safety switch. With your foot on the brake, try moving through the gears as you hold the key to start. Do It Yourself Diagnosis and Repair

Not sure what you mean by eng mod fuse. What's the year, make and model? What's the description of that fuse in the owner's manual?

Google it/utube its there

Doors do not open themselves, someone is messing with you or your vehicle is haunted

Possible partially plugged catalytic converter? The pop may be unburned fuel igniting. I would want to check the exhaust manifold pressure. Have a helper hit the gas pedal and back off several times and feel the exhaust flow, if it doesn't seem to increase in relation to the engine speed increases, and/or it gets extremely hot, compared to a normally running car.that is a good indicator of a plugged cat. If you also get a pop, especially if it includes a burst of exhaust as, that is an additional indicator.

Your best bet ,take it to a qualified repair shop

You probably need to replace your plug wires and cap

Has any work been done under the dash. Sounds like you have wire grounded to radio or something else the fuse sends power to. Maybe you could unhook hot wire to radio. if fuse blows again you know it is not the radio.

Big headache. Let an experienced professional handle it. Something maybe blocking circulation of the system, or a crack in the cylinder head. A few tests might reveal something-block test, compression test, radiator flow test. You could do it all with the proper tools, could even rent them for cheap. Was the cylinder head tested for pressure and straightness when it was off? So it is not losing coolant anywhere except by boiling off?

Transmission input shaft bearing.

My 2 experiences with limp mode was on a 93' Chevy. 1 time was the ecm, but it didn't reset until I replaced the ecm. The other time was the main electrical plug that comes from the ecm. The largest electrical plug on the trans. I unplugged it and there was trans fluid inside the plug on the 16 pins that connect the external wire Barnes to the internal wire harness of the trans. This required a new harness inside of the trans and replacing the external harness near the trans. Not an easy fix and may not be your issue, but this issue would "come and go". Fluid would short out the communication at the pins.

You mention that it acts like it jumped time. By that do you mean that every few revolutions it sputters like it's thinking about starting, but fails to actually run? Have you checked to confirm you're getting fuel? Have you confirmed you're getting good spark? Have you double-checked all vacuum lines and electrical connections to make sure all the appropriate sensors are plugged in? Do you have a scan tool with datastream mode so you can make sure sensor readings are reasonable? Do you have all the intake air tubing properly installed and secure? I'm not sure if the '99 Neon uses a MAF sensor, but if so, having that unplugged or having some of the intake air tubing not tight or with a hole somewhere can cause the symptom you describe as well.
