Jerks when idle or cold start


Asked by Apr 20, 2016 at 01:51 AM

Question type: Maintenance & Repair

Recently i changed car plugs (bosh) and plug
cables (bosh).

Reason was my car use to jerk a lot while driving.
Used not to accelerate well.

But after some days it again started doing but
mostly first 2-3 minutes after cold start.
And when idle....

What could be possible reason??

Do ineed to change engine oil now??

might be a vacuum leak. Does you car have a distributor cap and rotor? Change the oil regularly, most probably not due to your jerking issue though
