i noticed for a week now that when i step on the gas the car wiggles including the steering wheel on high rpm. especially on fourth gear. im thinking its gotta be the allignment. but what do you guys think?

at first i checked the tires coz i thought i had a flat tire but it turns out tires were low on air so fixed that problem but the car still wiggles. Did anyone had this problem before? can someone help me out?

my last resort is to get and allignment...

And do you guys know if PEP Boys do allignment on a lowered vehicle?
