yeah exactly fouundation ki hay aur agar from tyre say hay then chimtay bhi check kra lain....
brother check ur cam sensor is is working properly also check ammulater confirm in dono main say aik kharab ho ga.
there are lot of things which are to be checked first check spark then fuel injectors and plugs.then air intake.but if u start directly on gas which u can do first switch on the car not start it.press the button from gas to petrol then in 1 sec pertol to gas then start it if it start giving no problem them then pro is with fuel injectors or pump other wise check intake and spark.
have u checked the bearings of the rear tyres and may be it is coming from the exhaust some washer is broken.and for steering check the steering oil if it is decreasing then there is some leakage and check the rock ends of steerng.and for clutch grease the clutch wire.
