Motors A Nissan Primera With P0171, no idea what to check next

Aren't ECUs designed so the car will still run even if there's a serious MAF/lamda sensor failure anyway?

 

I was under that impression. I'm known to be wrong, mind...

 

Running lean, and black plugs with zero servicing, that's toasted rings. I suspect the oil scraper ring is stuck allowing a lot of blow by.

If it were lean with a vac leak, those plugs would be a bright white from running too hot.

Also check the timing belt tension, I wouldn't be surprised if it's jumped a tooth and hence sparking at the wrong time.

Walk away, just walk away.

 

Aye, bit of a shame really as the car in body terms, is still pretty mint. No rust, damage, glass is all good, locks all work fine.

Buggered it is, buggered it will remain. Also after going back for 4 days with no pay (we're talking petrol money here) I really cannot be arsed anymore.

Going to write this one off as a bad experience.

But oh golly gee, I get to play with a Citreon next. That ALSO doesn't get looked after.

Utter joy.

 

I would've given up after the 2nd visit.

What's wrong with the Citroen? That's a bit more up my street being French.

 

French car, take your multimeter with you, and soldering iron, crimps, electrical tape etc etc

 

I would imagine so, but a broken sensor is still there and making a circuit.

If I tried to crank my Tiburon (yank coupe) with it gone it would just refuse to start, then you'd get a terrible smell of petrol. With the duff sensor in it would run, but man, so rich it would do about five miles to the gallon.

 

White smoke, not sure if its cold weather or water vapor from a leak.

But don't worry, it is being driven everyday.

Anyway, to everyone so far (Krikkit, Kirk, mrbungle, sjamppo, AlienwareAndy, everyone else). Ta for the help so far.

I now really hope the owner crushes it. Just so I can watch, and feel better for not getting any petrol money for this.

 

Your welcome..... bring on the next one..

I own Alfas so im always getting my hands dirty

I lost a citroen to white smoke once... a nice golden CX with no rust.
Citroen service are horrible with old cars.

 

White smoke of either an exhaust full of water, or... well you know.. another walk away job.
