Car is running like crap
alright guys, i need help pretty badly. i completed my b16a swap last spring and i've had absolutely no problems until now. the other the day my car started running like crap. when i hit the gas off of idle it studders really badly sometimes. Sometimes it even begins to stall out. I'm not sure if its the spark plug or the wires, or the distributor cap. I was talking to a friend and he said if it was the spark the engine would just continually run rough. he thinks the coughing notchiness of the throttle might be caused by a bad fuel injector.
When the engine is in higher RPM, like above 3500, its fine, and runs completely normal. only near idle do i have this problem. i have to work about it almost coughing and dying out like everytime i hit the gas.
also, my motor mounts are worn out and i think the vibration caused by the way the engine is running is causing the motor to hit my hood. what are some good replacement engine mounts i could buy, maybe with polyurethane bushings?
once again, this is a JDM B16A in a 1998 Civic Ex Coupe, thanks for the help guys. I need some direction here on were to start, i've never diagnosed problems before.

Hasport makes some really nice mounts.

A 98 civic... You're in the wrong forum bro 
If you hadn't mentioned that the car ran fine before, I would have thought that it might be a timing or cam issue. Does your car lope at idle? Not as much power at lower RPM?
I'm going to take a stab at something. I don't own a vtec engine, but I gather that the vtec is switched on by the computer. Is it possible that vtec could be continuously on? If so, that would explain it. Since the vtec is activated at a certain RPM, does the ECU use the same sensor as your cluster tach?
And, if anybody can tell me why my vtec suggestions are totally stupid, please learn me. i like to get learned.
