hey, I know its prob a noob question, but I'm too lazy to search
BUT it seems like when I step on the gas a little harder than tapping it, the gas needle goes down more than normal. What can be the problem?
Also, if I only step on the gas a little bit, theres a hesitation. Could that be because of the throttle body? I know some symptoms of that being a problem is hard starts in the morning, which I havent had in a while.

thanks

 

When I get on the gas lightly, my car hesitates just above 2K. it will go up and then down and then start to pull slowly.

I have an intake and budget ypipe. My throttle body is cleaned out, did that twice already. Not sure what the problem is. I'm guessing it's b/c I don't have an aftermarket bpipe so there might be too much back pressure?
