2002 toyota sequoia spark plugs problem?

I just changed the spark plugs on my wife's 2002 toyota sequoia. Now the car stalls constantly. Whant could be the problem? I checked all the vacuum lines and they are all good and it wasn't doing that at all until I changed the plugs.


Did you use factory plugs? if not this could be your issue. Also make sure the ground wires on the manifold are tight.
