I've got a lot of vibration when I accelerate 1st through 5th gear normal driving. This recently started happening 2 months after my b16a swap. It doesn't feel like the motor is misfiring but I replaced the spark plugs and spark plug wires, still no help. wheels are all recently balanced, no vibration when braking, no vibration when I let off the throttle... looking for any help possible.

 

maybe your axles are bad or maybe bad engine mounts

 

most likely you axel!!

 

id just mak shur the CVs are lined up so when they spin there not unbalenced

 

I would say motor mounts, unless your lugging the engine. Axles don't vibrate, they do much worse when they're about to go.
