help needed

[kathy1]

I have an 2003 1.2 s micra, on cold start up the revs fluctuate badly and sometimes this causes the car to stall, I have changed sparks plugs, ignition coils, throttle body and mass air flow sensor, but the problem is still there.

Also sometime the car seems to loose power when driving this happen twice over a few months, and once the revs stuck on so we changed the throttle body and found the original was full of muck.

don't know what else it could be realyy hoping its not the ECU

stretched timing chain maybe kathy ?

Air leak sounds like.

Take off the upper timing chain cover and see if the chain adjuster piston is more than 9mm, if it is then its s stretched chain

 

[kathy1]

how much is that to get fixed?
