2G Hesitaion and dying

[Inkdlyfe]

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

sounds like to me your losing compression vacume leak or your being choked by too much air my car did that once for a period of time
and i had a crazy idol issue but in your case mybe your IAC is bad witch could cause excessive air flow or not enough depending on if its stuck open or closed its a possabilty id check that

Plugs , wires? Possibly vaccum leak , do a compression test after you have tried all those

+one on a possible loss of compression. However, do you know where the buzzing sound is coming from? Is it manual or auto?

Figured it out after warranting the cas 3 times i figured it out so i traced the blue with red stripped wire back to the harness and found out that it wasn't connected been broken off due to the rear motor mount being bad fixed that up and now runs like a champ no more p0340 ! And starts up on its own strong

The buzzing sound I havnt drove it yet but everything else is fixed and will move fine so imma take it for a spin and see if the buzzing is still there
