HELP PLEASE !!! I've got a Primera SE+ P11-144 2litre petrol Estate. It starts from cold no problem, then after about five minutes or so stalls at idle & is temperamental to restart......if i lift the clutch slightly i can sometimes get it to refire without turning the key, & have to keep the clutch fractionally up to keep it running at idle. It had an idle control valve just over a year ago & although very similar symptoms, this doesn't seem quite the same. Bizzarrely this problem started after i had a new rear exhaust box fitted, but i can think of no reason why this should be in any way a cause. My mechanics have checked the hoses etc for air leaks, cleaned the throttle body, & run diagnostics with no results (probably due to the fact that the engine management light doesn't stay lit so isn't picking up any faults). It's running very rich at idle. It's been suggested that i get a throttle body with sensors, or that maybe it's the mass air flow sensor. If anybody has any suggestions i'd be grateful.....................................................

Are you getting stalling when slowing for junctions?
This is a common symptom of a worn MAF. How many miles has the car done? The MAF typically wears out between 70K and 100K miles. Genuine Bosch MAF assembly for the 1.8 available on exchange for around £50 from Eurocarparts and Andrew Page. You would need the sensor from the 1.8 MAF assembly. T20 security torx (star with a hole) driver is required. What year/plate is your car? Might be worth trying the idle air learn procedure from the Service Manual. SR20 Engine Control Chapter, Page 47. Very easy. |

Yeah, stalling at junctions & whilst sitting in traffic.
It's 'Y' registered, July 2001. Only done just over 87000 miles, which appear to be genuine as i've got the full service history. I spoke with Eurocarparts today & it came in new at £250....ouch !!! But i'll try shopping around again to check out exchange prices. There are some OEM MAFs on ebay for around £40/50........although i've heard there can be problems with non genuine parts of this kind....??? |

you don't want to ask eurocarparts for a 2.0ltr maf as they cost a fortune ask them for the 1.8 one as mentioned in the post above yours...
and yeah unless you find a cheap genuine one on ebay, avoid them

The pre-2001 1.8 MAF can be made to work.
Yours will most likely have the thermistor on the MAF. Also identified by having 5 wires on the MAF plug. Older 144s have 4 wires and an external thermistor. The thermistor is held in place in V-shaped terminals. Spread with a small screwdriver, move to replacement sensor and nip up with small pliers. Plenty of people have used the 1.8 MAF on the 2.0 with no problems. Moving the thermistor onto the exchange MAF also works. Can't get pic working.
