my car startles and dies when turning corners and misfires, help

[maku_gx]

hello there

I was at VIR when it started getting worstwhen i go straight, its fine, except when you ask too much of it, like at 6rpms its kinda unstable.

when i turn corners, it feels like the G'S become null all of a sudden, and then from one sec to the other it will catch again, specially when the G'S decrease tot he middle.

someone said it could be the grounding, It sounds like it could make sense.

the pump 1, died when i got back of VIR in the middle of the highway, it seems after CUTTING the FILTER attached to the WALBRO 255 pump, something stuck it.

but it had the same problem, bought a NEW ONE, and that same problem still going on.

any ideas?

thank you very much.
