I bought this 16v 4 cyl car about a two weeks ago it was not run for over a year before I bought it. I barely managed to get his car home after buying it where it died in the drive and. I just got this car out of the shop for the would not start problem. Now it starts alright and runs fine for about 20 minutes then starts to miss and then dies. if I turn the ignition on and off a few times to cycle the main fuel pump, it will run again for a couple of minutes. If I leave the car idle it seems to run for as long as I will let it. I've replaced the main fuel filter, made sure I could hear the prepump run, took out the prepump assembly to make sure the inlet screen was not clogged, I've run the car with the FPR outlet going into a gas can to make sure that it was not stuck closed and pumped 5 galons of gas out of it with no problem at idle. I don't have a fuel pressure gage but when the car is running during the 10 minutes it will handle WOT acceleration fine, it just starts to miss driving at about 35-40 mph and then stalls out completely it acts like fuel starvation. I'm thinking O2 sensor or maybe aan injector clogged but then again it drives fine for a little while...any ideas?
