why is my accord slow
ok, this is about my accord but i dont know if it belongs in this forum, but i didnt know where else to put it.
ok so every time i slam my foot to the pedal, it takes a long while for it to actually gain power. but when i gradually step on the accelorator pedal, it feels like the car has more power. i heard this might be due to the fuel pressure regulator cuz when i slam on the accelorator there might not be enough fuel. what can i do to help this problem. is there a performance fuel pressure regulator, if that is the problem.

I dont know about your accord but when i slam mine to the ground.........im.....iiiizzzzzooouutttttttt!.
I had a similar issue but my car actually started to buck and shit.
The CEL came on and I assume I had a clogged fuel line. It went away after a couple of nights of sitting in the honda dealers garage. They couldnt find the problem at all.

it might have to do a lot w/ throttle response. do you have an aftermarket intake? if things arent clamped down properly air might be leaking and cause you to have to wait on a good flow of air coming through. and yeah, if you have an auto it will take more time to pick up.

**WARNING: SCIENCE CONTENT** (Mythbusters fans?)
The lag is just the transient while the ECU adjusts for the sudden change in throttle position. It shouldn't be that noticeable but it takes the fuel system a few moments to catch up. Think about what's going on inside the engine. At the instant that you nail that the throttle there is a very sudden flood of air into the engine. This results in a lean mixture until the air mass meter and O2 sensor tell the ECU what's happening, at which point the ECU adds fuel. Lean = less fuel = less power. Some ECUs actually revert to open-loop at WOT which brings the mixture all the way over to rich. Rich = air is displaced by extra fuel that won't burn = less power, too. That's to protect the engine from pinging and unsightly CELs. So I really doubt that there is anything wrong with your car at all. You can check for vacuum leaks as others said but otherwise just go a little easier on the throttle.
