N54 just revs up and down
Hey so I went to reinstall my jb3 tonight and may have hooked it up wrong since it's a older one.. So I took it out and now when I start why car it just revs up and down quickly with the half power light on the dash.... Anybody know what's up with this? Thanks

It's a pnp it worked perfect before .... Only reason I took it cause I put new plugs in and it was still runnin shitty so I took jb3 out .... But once I cleared codes it was good.!
