Replaced fuel check valve and pre-pump. Nice, new spark plugs. Throttle body cleaned. The car takes multiple attempts to start and keep running when cold. Will run for 1-2 seconds on first attempt. May run for a few seconds more on second and third attempts, or may require some slight revving to keep running. Occasionally takes 4-5 starts to finally get it running. Will sometimes even pulse a little when I'm going 10-30 miles an hour. Once I get it up to higher speeds, it does fine. No problems on the highway. Idles relatively well at stoplights, no excessive variation in rpm. No check engine light. Any ideas??
