i have a stock civic cx that i bought with a blown motor in it. i recently put a used motor in and it statrts a idles perfectly. the problem is once i get over 1/4 throttle it just boggs it won't go naywhere. i have already checked timing and marks are on the money. map sensor voltage output is where it should be. i am not sure where else to go, any help would be greatly appreciated.

thanks

are you throwing any codes? check tps and o2 sensors

Switch your MAP sensor and your TPS sensor and tell me what happens. Takes 20 seconds

double check injectors could be a fuel problem
