Exactly! It is in open loop until it sees an output from the lambda probe 
which doesn't happen for up to a minute or so in most cases. In fact, since 
our lambvda probes are of the early vintage, unheated design, the ECU can 
even drop out of closed loop on a warmed up car that is left idling for a 
poeriod of time. The exhaust stream can get too cold to hold the system in 
closed loop.

Probably the best way to diagnose a bad fuel filter is to replace it. It may 
or moay not be your problem. It may be part of it. The best way to tell is 
replace it and stop wondering about it. If you do that and still have the 
problem, at least you can look elsewhere.
