Hope you are well

Is the steering movement heavy? and does the noise increase when you steer it all the way to the right & left?

[pwuser149401797684]

No brother steering is ok plus swift comes with electronic power steering

Check for vaccume line leakage... including EVAP system lines.

Problem solved..changed the inlet manifold

[salmanbari85]

My swift 2015 is having the same issue, loud noise of engine on cold start. Did you identify the problem yourself of inlet manifold or from any mechanic? also what was the cost of fixing this?
