idle issue

[jw 325ic]

hey when i start my car i have to lay my foot on the gas pedal to keep it from stalling. when cold it stalls at idle and when braking it tries to stall, but only when cold(like right on start up, first few minutes). it started this after i did my motor mounts and transmission mounts...since then ive replaced the spark plugs, various vacuum and fuel hoses, new fuel filter, and have a new intake boot on its way. the current boot has a very slight crack which i covered in tape and nothing happened. Could it be the throttle cable or TPS? i mean ill see what happens when i replace the intake boot and clean my k&n. Coolant is clean and fairly new, but the plug wires are old. Every sensor plug is plugged in (didnt get unplugged from motor mount installation) but do minor cracks in the boot cause problems like that? After the temp needle moves out of blue it idles at 700. when i come to a stop though, it surges twice then smooths out. My ICV vibrates. I replaced the VC to TB breather hose...nothing..new wires? tps? thermo temp sensor?

it feels slightly underpowered when its cold and acting up. its never felt underpowered at cold. at times when i start it warm it surges for a second then catches at idle and feels like it has full power. also the oil pressure light may flash right when starting the car and stay on for a second or two then turn off. after i did my motor mounts my radiator got out of adjustment so i re-adj it, but the fan was hitting the radiator... alternator? i dunno sorry im all over the place just tryin to give out as much info as possible. thanks

oh and it has fairly new belts
