i have a b16a , when i cruze at 30 mph and put it in 4th gear and floor it , then it seems like it wants to go then it feels like its pulling something then picks back up and keeps doing the same thing until i get into mid vtec . meanwhile my air fuel goes lean when it feels like its pulling something, then it goes
into the yellow it picks up again and it never seems to stay rich except when i start the car its got to be something stupid
