Cruised the town tonight for a good hour and a half. Got on it a couple of times. Lots of stop and go with the lights, etc. Started to head home and there is a bridge I drive under that I like to get on the car a little and hear my exhaust roaring. Anyhow, I'm in third and get on it, but the car starts surging and doesnt rev up like usual when I get on it. It wasnt surging hard, kind of like a miss, but it was like there was no power. I pull up to a red light(it idled normal), light turns green, I take off normally in first, shift to second and give it some gas and it surges the same. I've had this car a month and I dont need anything wrong with it yet

Into third, still surges. I drop my brother off, and am kind of driving it fast through town. I've got one more street before I turn to my apartment. I get on it through second and third and it seems to run fine. Was cruising through town bogging it down? It's got a bigger cam in it, with higher compression pistons. I'm a novice with a semi-built car....

Any ideas? Temp gauge was normal. I'll start it tomorrow and see if anything changes.
