ok i got the damn car to stop the intake backfire, but now i replaced the coil for it to stop dying when it warms up. only thing is that it still does it even when idling. like, you can start it in the morning and it runs fine, but as soon as it gets warmed up, it starts to quit when you rev it, it bogs down like crazy. i think my choke is all messed up. any advice? or should i ditch this engine and get a better one?
