Hi. I have a 2003 civic DX and I have a problem with the gas pedal. The pedal is a little hard, and when you go to press the pedal, you have to give it a little force to start moving the pedal. It's not easy to start the accelerating slowly. I read on the Internet that some people have experience this problem on other cars and their problem is that the throttle valve gets gunked up with carbon deposit. I looked at my throttle valve and it has something that looks like carbon, I think. I was wondering, does the throttle valve have to be clean and the walls?

It sure wouldn't hurt to take some throttle body cleaner or seafoam, doust a rag and wipe that badboy down. Open the butterfly and clean the edges of it (the blade looking thingy) and make sure you clean the walls of the throttle body where the butterfly is going to be closing. See what that does for you.

Is it easy to remove the intake?. I think is more easy to clean outside. On the internet it says to use carb. cleaner and I don't know if the carb. cleaner gets inside the engine could damage something. Any tips?

It's very easy to remove the intake, carb cleaner prolly won't hurt but some might object to that. I'd use just about anything on mine

My whole intake is covered with some black stuff. Is this normal?

Yes it is normal for that to happen over time... just clean it out and your throttle sticking should stop. Just get throttle body cleaner. That is what it is meant for..
