Alright, I have an automatic LS and well I've only really floored it a couple of times since I bought it like a year and a half ago. Now it just doesn't feel strong as it was when I bought it anymore. Can anyone help me with this by telling me why it's driving like this. Would a valve adjustment help out a little since I haven't had one done yet since it's snowy over here, plus I'm lazy and broke. I don't believe in stepping it hard on automatics and I only step on it to around 2.5 RPM and then let go of the gas and let the gears switch over themselves. Am I giving it too easy on the car or something? Any help appreciated thanks guys.

 

It could be that you are getting used to the speed. Maybe it's time for cams

 

Try a tune up!
