So the past few days it hasn't been wanting to really go past 4k with out falling on its face I can kinda ease past it but some where along the lines of 3800 and 4200 it really starts to studder so i just been keeping it under those numbers now today it's really bad for some od reason . It seems to like want to not start eventually it does but back fires and rpms go nuts then idle perfectly fine but when putting it in first it wants to die like right away this is a 5spd not a auto so its not a safety switch . I managed to get it home BARLEY I'm not smoking at all or leaking I'm in time all that . I'm not turboed right now so its not a boost leak . Not really sure what the problem is I also noticed this really werid buzzing sound. It seems to only make the sound when actually in a driving gear and only at first kinda like a bus saw sound but only at low rpms and only in a drive gear not in nutrul I got the car home so thats a plus but i still need to get this fixed any clues ? The car cranks and cranks and cranks then eventually fires but i used start fluid to get it home shoots way up to like 4000 rpms then gradually comes down. 420a
