I just recently got a new motor for my 00 civic si...for some reason when i step on the gas the car seems to hesitate i cant step on the gas fully otherwise it would start throbbing like its about to stall... and it doesnt really excede over 30-40 mpg....I'm not sure if its only because it needs tuning or if theres some other probs..can anyone please help me i would very appreciated..thanks

check your plug wires and firing order. bad wires will bog.

make sure the plug wires are fully inserted on the valve cover and dizzy cap
