first and most obvious problem, is over 2500 rpms, (in gear or nuetral) my transmission vibrating enough that my dash starts to rattle
i got new clutch and new transmission brace installed in febuary and i checked the drive shaft for play and that seemed fine (figured it would be since it happens in nuetral as well...) any ideas, help is appreciated

also, my smog pump hose keeps comming off my smog pump, would that affect anything on my car, because shes idling real rough latley and misfiring when shes really cold.

Thanks for all help

 

any help?
