Car shuddering/vibration?
Just wanted to see if anyone could help me out. I filled my trans. mounts w/ polyurethane about a month ago, and recently have noticed that for the first 5 minutes or so after starting the car, it shudders right after I let off the gas. Like right when I pull away, let of the gas, and coast to a stop, the engine drops rpms fast, almost to a stall (shaking pretty badly) just before I come to a stop. The funny thing is that after driving the car for a few minutes, it doesn't do it anymore. I know it isn't from the poly mounts, but I'm assuming that I can just feel it a lot better now. Does this sound familiar? The only other mods I have are a K&N drop in filter. Thanks.
Also, does anyone else have bad vibes w/ poly trans mounts when going slowly in reverse? That's really the only time I feel the vibes from the mounts. Kind of annoying, I'm thinking about taking them out.
bump. Nobody?

Sounds like it could be something to do with the cold start cycle.
Maybe a vaccum leak(hoses rubbing together some where)
Im not sure but I think the ecm ignores most sensors (Run in a closed loop) till the car reaches a certain temp.
