car is a 03 reg primera p12 2.0 petrol
Been having this issue for ages, took it to a couple of garages and they cannot diagnose the fault.
When starting the car from cold the revs drop and sometimes it stalls, sometimes it doesn't, then the revs go up to normal. sometimes I have to rev it to prevent stalling.
when cold the engine feels like it has no power, and when driving with the engine hot or cold and you come to a stop and let the revs drop to idle, they SOMETIMES drop to almost 200rpm and then go back up to normal 800rpm.
That's the symptoms, things I've tried,new MAF sensor, disconnecting the MAF, disconnecting the battery, tested the MAF wiring.
The car had a diagnostics and only came up with a NATS malfunction (alarm immobilizer system), tried the other key, tested the emissions and it smelt of sulphur and it failed, revved it for a few mins then passed with flying colours.
Checked all live data on diagnostics and everything's working as it should.
I rang Nissan dealer today (last resort) and they said that they probably wouldn't be able to find the fault if nobody else has (it's been on 3 different diagnostics machines)
anybody give me any ideas what to do next?
