I have to agree with Todd up to a point, With any cold start problem one should look at plugs, plug wires and cap as replacement items if they have not yet been replaced. These should be replaced before the temp 2 sensor. Given that you have done this work and the van runs good warm but bad at startup, the next things is to pull the o2 sensor wire and see if it runs as good warmed up without the 02 sensor. If it does I would look at the plugs before starting it cold and do a sniff test on each cylinder? gary --- Todd Last <rubatoguy@mindspring.com> wrote: > When I had this problem it turned out to be a bad > (intermittant) plug wire.
