Pull the vacuum line off the fuel pressure regulator and smell for gas. If you can smell gas in the vacuum line the FPR has failed and needs to be replaced.
ok inspected vacuum lines for fuel regulator found one 90 deg. boot not pushed all the way on, the last three days car has ran without any of the warm up stalls, but we are having a heat wave hear and temp is 73 deg. plus in the mornings, it is suppose to cool of with in the next couple of days so going to feel better if can run with out a warm up stall with cooler temps, thanks for the advise and if I get another stall I will check for gas smell in vacuum line
ok, got around to looking at the bonnie again replaced the fuel pressure regulator, car ran good while it was in the 70'* in the morning when it got to 59 one morning it still stalled when reaching warm up. any more thoughts out there ?
