[Weekend]

I have a 1996 LHS with 87000 miles. Last winter it began being difficult to start on mornings below 25 degrees F. Sometimes it will start if I hold the gas pedal down (cranking several times) and sometimes it won't. If it starts it acts like it is flooded for a few seconds. Once it has been started or or the temp reaches 30 degrees it runs and starts fine. I have replaced a defective oxygen sensor and the Mass air sensor without helping. There are no error codes listed. Any help would be appreciated.
