Lopeing under load

[batmmannn]

I called a friend of mine and he said it could be dirty injectors. I am unsure if I should call it surging or loping. It's like when you are going it starts to rock you forward and back like it surges and then lets go on a very rythmic basis. Not there in hard acceleration or gear downs just as you are under light to medium load. Seems to get worse as the car warms up.

I sucked a lot of stuff through the throttle body cause of a rats nest in the air cleaner. When it happens it rocks you like your in a rocker forward and back it's annoying as hell. Its not so much a miss as like you are pushing on the gas lightly and then off and then on and then off about once every half second. My cams are dead on cause I just did the timing belt.

Where is the fuel regulator you speak of? Thanks, Scott
