1G 1g gsx front end jerking around??

[Xtremboost87]

So I feel like something is broken in my front end but not sure what. If I take a sharp right hand curve the front end and steering wheel jerk left and right really bad. And at certain speeds the front end gets pretty wobbly. At lower straight speeds it rides fine. Also if I try to go up a hill the car doesn't want to go. It'll hit full boost at like no throttle and bog down really bad. Only does this going up a hill... Any thoughts on either problem?? Trying to make the rest of my trip home and need advice asap!

Also when this happens the exhaust temps at the manifold are reading between 14-16 on the gauge so 1400-1600 degrees?? Just bought the car so don't know much about it yet. No idea what the air fuel ratios are..
