420A Dies or wants to die over speed bumps

Guys I need help!!! My eclipse always wants to die or it dies when im coming to a
speed-bump.

The first question is, is your battery bolted down?

Yes it is, the battery is also snugged on with by the intake. It literally has no room for it to move.

Along with Steve's post, do you have an insulator over the battery + terminal (so it can't short against something)?

Good question, your talking about an insulator sheet? Or the covers for the terminals?
i do not have that now that i think about it

Covers for the terminals to protect them from shorting against something as well as help reduce corrosion. The positive terminal shorting against something (like the hood when battery is not bolted down) is a common cause of engine dying over bumps.

I mean covers like these:

Covers

Yeah i don’t have those. ill try it out. And yeah maybe it hits my hood. I never thought about it

Or less likely: Some loose wire/metal touching the alternator's big + cable which goes to battery + (and therefore ignition).

Yea, if it's not the battery hitting the hood it gets a lot more difficult tracking the cause down because now all sorts of things are potential causes starting with all the power and ground connections and wires.

Hmm yeah i dont think its my hood, i just re painted the underside of my hood. And i don’t see any marks.

Last owner did say he replaced the alternator. I’ve had my 2g for about a year. And it always wants to turn off over speedbumps ONLY

It may also be a loose ECU connector. I had that issue years ago.

engine and trans mounts are ok? if they're really loose it can tug wires, also check all connectors that they're good and tight and possibly try the pins out, specially on crank, cam sensors and ignition coil pack

Actually no 2 of my motor mounts are blown i replaced 2 other but i didn’t have time. I did think about that though. The wires pulling.
