Car stalled on freeway after going over a bump.

Asked by RobTheProspect Sep 30, 2016 at 04:42 PM about the 1999 Mazda MX-5 Miata Base

Question type: Maintenance & Repair

No other engine or transmission problems that I know of. Seemed like an
electrical issue. The airbag light came on and the car seemingly stalled
while going 60 mph after hitting a bump on the highway. I popped the
clutch and it restarted, but the computer seemed to be having trouble
regulating the fuel flow as the gas pedal felt very jumpy/sticky. The problem
went away after I got on the off ramp and slowly came to a stop. Now I
can't reproduce it. Any ideas?

May be a loose ground wire. This possible could be the engine block to frame grounds or any other grounds or a loose Computer ground or a electrical connector somewhere that is barely connected. I would check them and push all connectors tight.
