M35 Spat The Dummy

[ddrallystagea]

Hi all

My stock M35 decided to run like lumpy porridge for my fiancé on the highway to canberra yesterday.

It got us home but is clearly unwell. I can still hear turbo noise under acceleration in the normal spots, but it has no grunt and idles really rough. Also for the last few weeks it's been developing a bit of a flat spot between 3.5-4k. Thoughts?

From reading other similar posts I'm thinking afm, hoping it's not the turbo... No engine light and it starts and runs, just badly. Do they typically spit hoses?

Any suggestions would be great!

Cheers

try cleaning the afm

You should be able to check all the basics yourself, check all the vac lines are on, look for loose hose clamps, make sure the intake is tight and the afm is plugged in properly. The stock hoses are fairly robust and don't normally split.

There is a good chance the turbo threw a few blades unfortunately, is it louder than usual?

I would say either a hose or pipe on induction side has come off, or afm requires cleaning or replacement. I've had both happen recently at different times. Also, some of the guys on here have gotten new afm off amayana.com (i think thats what it is called) and I would recommend this over nissan. Nissan charges $309 retail!!!

Thanks guys. Afm out to be cleaned in the morning, hoses look ok, although there's plenty of them so I may have missed something. Turbo doesn't seem louder than normal, so I'm keeping my fingers crossed! Will update as I go...

Hi all

Cheap success! The turbo's fine! Old plugs had caused a couple of coil packs to pack it in. All fixed, purring like a big fat kitten again.

Thanks for your suggestions.
