engine misses
Ok I finally got the new engine put in my 93 F150 it runs good as long as your in the gas but when cruising at a steady RPM I notice a miss. Spark plugs wires cap and rotor was chnged with engine. I pulled codes and all I get is 225 knock sensor (twice in a row) If I pull EVP wires off it runs good but I et CEL. The egr system seems to be working I can see the valve opening as I rev the motor. I also replaced the EVP. I've sprayed carb cleaner on vaccume fittings and noticed no difference. The exhaust was also replaced with the motor.(stock except single cat instead of dual. I need to find this problem I' at my wits end .Any help would be greatly appreciated. thanks .
