HELP bad O2's/Vaccum leak??? I have a 99 Trans Am M6 that's not throwing any codes and whenever I shift into 2, 3, or 4 and under moderate throttle it feels like the car hesitates to go for a second or two then catches up with the throttle I'm giving it. It'll still accelerate, just not at the throttle I'm giving it until it stops the hesitation feelings. And no it's not like I'm shifting into 4th at 20mph then trying to gun it and underdriving it lol but I've seen it could be bad upstream o2's, vaccum leak, loose intake bolts or fuel filter. Any help will be REALLY appreciated
