2013 Nissan Pulsar St-L Idle Hunting

[YoungMoney]

Hey guys,

Quick questions to the engine savvy people, just over two weeks ago i purchased a Dealer X-Demo 2013 Nissan Pulsar ST-L with about 6000 kms on the clock, after a week of driving i started noticing it had a rough idle whilst stopped at traffic lights, i looked at the RPM Tacho needle which was moving between 600 rpm to 800 rpm sometimes eventually it will settle at about 700 rpm but still move ever so slightly, whilst my foot is on the brake i can feel the engine like shaking slightly, as if its about to stall but doesn't. Almost as if it just can find a idle hot spot.

Yesterday I took it to a Nissan service centre and go one of their techs to look at it, he took it for a test drive and said whilst driving, "oh these models just have a rough idle, not much can be done about it" he said he would hook it up to the computer and re set the idle. I drove it home and felt like it was fixed, didn't really see the Tacho jumping around nor feel the shake, however this morning i drove it to work and it came back again. I rang another service centre to get a second opinion and i spoke with a knowledgable person there who said last year Nissan did an upgrade of the ECU but it caused it hunt whilst in idle. Hopefully he can help me so I am taking it to this guy tomorrow however i just wanted to get some quick advice in general.

Should the RPM needle be moving at all? and should i even feel that stalling shake on the engine? To me thats not normal, i do not want a new car with that sort of an issue, it doesn't seem right to me.

Thanks in advance

no it doesnt seem normal.

Jump on Pulsar Group Of Australia and make a new thread. plenty of experience and skilled ex-Nissan employees there. we would love some problem solving on the new C12 platform.

Umm, tried raising the idle? It might have an idle screw adjustment like the older cars. Or maybe it's all ECU controlled now.

Perhaps some build up on the throttle body?

I would definitely keep this in mind, but doesn't really seem like an issue to cause unstable idle. and I don't think jukes have been having issues with gunk build up.... not yet anyway...

It's a new car. It's not an issue to fix yourself.

It's for a dealer. You are doing the right thing by going to a different dealer for second opinion.

Oh 2013, yeah get dealer to fix that up. ^ What he said.

New car, still under warranty. Take to dealer and tell them to fix it. Rough idles aren´t normal for cars like that. Don´t let the mechanic convice you otherwise.

Yeah, 106000kms, maybe build up on the throttle, but not 6k kms.

Take it back and make em fix it.

Direct injection motors and EGR motors are terrible for intake and plenum crud.
