Got a 00 civic with y8, When im driving in any gear, if i let off the gas and slowly press it it jerks a little before going, i need to replace my crankshaft sensor, But also have a bad motor mount which do you think this is from or something else? im going to end up replacing both just looking for some input

 

Replace/fix the sensor problem and then go from there.

 

Did you recently purchase your car or have you had for a while and the jerking is a new issue that wasn't there before?
