car vibrate during idling

[nicholasoh]

Hi,

When I start the engine, at idling stage, the car will vibrate at a stage whereby I can see the seats 'shaking'. My idling rpm is around 600-700rpm and sometimes 500-600rpm. It only happens after I did a k20a head swap and kpro installed (before and after tuning). My mechanic says that it is due to a faulty kpro as he could not find issues with other areas such as TB, mountings etc.

Can I check if it is really the case? If so, can I send the kpro for repair? What will be the cost of it?

My current drive is base auto and setup is k20a head, k20a3 lower block, itr header to exhaust, itr manifold, kpro.

Thanks.

Vibration has nothing to do with the K-Pro. Automatics are not supported and that is most likely the cause of the problem.
