Ok been researching and found some things related to the slack I have in my throttle cable going to adjust it tonight. That said basically what im getting is if say im leaving a light and i want to get on it and i mash the peddle, its more of a build up like say the boost gauge on knight rider ha ha. I was in a couple cars the other night and both had immediate response not a build up. Now if im over say 2 or 3k rpms the response is fine its just off the line. I just recently installed a cam and this problem was persistent even before the cam but i rarely drove the car, im back in it more and this is driving me crazy. please help!

 

I had the same problem with mine. I cleaned the mass air sensor and it worked perfectly after that.

 

I cleaned mine the other night, probably going to give it another working over this afternoon. I also seafoamed the car and its running much better!
