hi i have a problem with my car can anyone help . my x type 2.1 v6 2003 has  started making a popping sound coming from air intake  it makes the sound on idle and the revs drop then pick back up if its left idling it will keep doing it but when i rev it goes away what can this be i know its not plugs coz i just changed then 2000 miles ago.

I bought the same model last week and I am hearing the exact same sound. There is a video clip posted in this forum and people have commented, but no definite answers. Solved yours yet?

Have you solved your issue yet?

It sounds like mixture at idle so I would say you have a small hole--a split pipe etc 

on the induction side so I would check that first .????

Thanks for the info. Took out the flexible hose today, but nothing wrong there. Also got a spray to clean the air sensor.

The other issue is at around 60 and in top gear, the car will start shaking if you try to accelerate.

i just had an o2 sensor go so i dont know if that would make the symptoms

Shaking could be caused by wheel balancing or a worn engine mounting, simplest things to check first.
