I'm working on a 2006 Suzuki forenza. I have new plugs and wires, timing belt, camshaft and crankshaft sensors, catalytic converter, and the first o2 sensor from the engine. it runs fine in park when I accelerate. When I'm driving and accelerate soft it's ok. But if I accelerate hard to pass on get onto a freeway it sputters .what's the problem? I'm thinking the ica. If so can I check it? Thanks for your time and knowledge

USA car? y/n what engine,?
sputters, not bog, do you have full power wide open throttle.
sputters means to mech, MISFIRING
if it is misfiring the OBD2 scan tool tells you it is, and even which cyclinder fails like P0301, = cyl, #1 misfire.
what is and ICA, there is no ASE listing for ICA< so you typed it wrong, my wild guess, Idel Air speed controller is yes ,that is not cause of sputter ever.
Bogging means like dragging 10,000 pound weight or pulling 2000lb boat up PIKES PEAK, CO.
here is a list for misfire, (takes tools and skills and tests to find it)
if bogging , add, bad MAF sensor, and low fuel pressure.
