Evening chaps, just got run off the road by someone who clearly felt they needed both lanes, i hit a pretty deep hole in the road and my 82' n/a cut out and ground to a hault!! i looked around the engine bay, no signs of anything obvious! tried to restart and it fired up fine???

So dear rennlisters, what might cause a cut out when jolted?
i have an induction kit fitted and afm isnt braced properly yet, otherwise stock.

My 83 would cut out or stall every time I hit a large bump or braked really hard. Turned out to be the reference sensor plugs/receptacles behind the intake were so cracked electrical contact would be broken. I zip-tied them together and never had another problem. Same thing can happen with a loose ground, harness short, or failing DME.

Sounds electrical in nature of course. Shook something like the reference sensors as above or the DME or a distributor or something like that is where I would look first. The DME relay and the DME board itself. The boards sometimes have cracks and loose pins etc anyway so a jolt could certainly bring about troubles. Hall sensors if they are on your car can be another place to check. I would also closley look at the battery, battery mounts, cables too.

thanks guys, ref sensors are brand new, so will check grounds and fuse box/relays etc.

My car would cut out ended up being the fuse box. Check where the connectors connect on the bottom side, inside the car .

On my car the cracked plug was on the harness side, and failed to retain even a brand new speed sensor correctly. Double-check that yours are in good condtion.

How is your distributor cap / spark plug wires?

maybe the afm just flopped around abit inside on the swinging door and upset the computer.

Is your battery strapped down well?
