car-ae86
motor-4age bigport with rwd manifold
problem-whilst driving tonight my 86 started to drop in revs for a breif second when ever i went over a bump on the road,at a latter stage when on a bad
section of road it made the motor stall,headlights,music etc was still on,started fine off i went,this then happened once more before i made it home.I checked that various plugs and spark plug leads were on properly,battery terminals are tight,when driving on a smooth road it hauls ass like before,just bumps gives it issues,no warning lights or anything came on on the dash so alternator should be fine?so got me thinking a loose or worn out plug,sensor,
or earth,could someone point me to which ones could possibly cause this bullshit,stingin to drivveeee (colour and location etc would be awesome)
