just brought a r reg v70 drove 200 mile to get home,it was fine.slammed on brakes to check abs and now it misfires some one please help

 

Maybe worn fuel pump relay ? at a guess but there could be many factors what could make this happen sorry cant be more help

 

Hello, What's an r reg? Look for disconnected hoses, large and small, which may have been strained by slamming on the brakes. A bad motor mount can aggravate engine movement. Any codes or CEL? Check the condition of the plugs.
