I have replaced the intake air sensor,fixed a loose vacuum hose to the breather tube to the cam cover, no air leaks to the air filter. But starting it is slow. you have to crank and crank and I noticed the fuel gauge drop from 3/4 to zero for a half second, then nurse it to run,after you can get it to 1000-2000rpm it'll run better but still stumble at low rpm.Idles smooth. Once it hits 3000rpm it'll run great.
Any ideas??
