How can anyone answer that? Perhaps yer putting diesel in instead of petrol? You havent said... Young whipper snappers... :-p
Tish posh...
I was gonna suggest if yer near Birmingham and don't mind potentially destroying yer ECU, you could pop round and I could plug the laptop (with Blazt) into the consult port... but alas, i'm not sure whether it'll work on your car? What's your engine? I've seen references to this thing working on a GA16DE engined Almera - whether it'll be suitable for a Primera 1.6 is anybodies guess...
They've had suggested, MAF Sensor, O2 Sensor, Fuel Pressure etc...
You should be able to check how your O2 sensor is switching, and indeed whether you have any fault codes stored in the ECU - Got a Haynes manual? It involves bridging two points on the consult port with a piece of wire.
Other people on the forum suggest that for whatever reason, the ECU has gone into limp home mode and try resetting the ECU!
Of course, there's always the Nissan garage - getting them to plug into Consult and getting any information... course, that's a lot of money, and you can at times be relying upon an untrained monkey to work out what the values mean. I do remember Westway Nissan in Coventry being pretty good (but the branch at Stourbridge were a bit crappy).
Then of course there's also putting your trust in me or someone else with a copy of Blazt and a laptop who should also be able to read all your sensors for free through the consult port. Of course, it's not been tested with your car, and I wouldn't like to take the risk. My own car? Sure, why not...
