Ive got a zafira 1.6 16v z16xe engine fitted, the problem im having is it idles erratic now and then and sometimes cuts out, it started doing it about every 1000 mile then its got worse until it was about every 30 mile and i got fault code 0130 - low voltage on front lambda, i looked at the live data from the sensor and it was showing very low, i was lucky to have a new sensor so i fitted it, straight away the readings returned to normal and its been about 800 mile and the problems back again, the car drives perfect and idles perfect but just now and then when idling it starts to fluctuate and sometimes cuts out, sounds like a missfire to me and the car feels sluggish when pulling away when it starts doing it making me beleive its a missfire, the car done it yesterday when we stopped at the lights, idle was fluctuating beween 500 and 800 but didnt cut out, the car strugged pulling away then after a few seconds went perfect and drove perfectly home with no problems at all, idle returned to normal, scanned it with opcom when i got home - no codes stored, The Spanner light has never came on when this happens, only lights that come on are the coolant light flickers when the revs drop below 500 which i think is normal and the emmisions light comes on when the cars not running if it cuts out,

Things ive tried so far are :- clean throttle body out including the 1mm hole that was blocked and all pipes, new genuine EGR, new genuine spark plugs, tried 3 genuine coil packs, new delphi crankshaft sensor, new coolant temp sensor, new temp sensor plug with gold tips, New NTK lambda sensor, Ive removed every connector and tightened them all up, ive checked readings from MAP sensor and they look perfect, air temp sensor data looks correct, im running out of ideas, only other things i can think off is the throttle body is past it and the built in idle control valve is sticking or dodgey ECU, Can anyone offer me any advice on this problem

These are notorious for faulty mass air flow meters, fit a dealer one they are about £100 but well worth it, factor parts aren't good enough for these

My model does not have a mass air flow meter, it has MAP sensor, the readings from this look fine, even removed it and checked it wasnt blocked but it looked fine, ive checked it for leaks and everything looks fine

Hi,

Sounds like it could really do with going on a scan tool.
As it sounds more like an emissions problem EOBD will be fine.
You need to be looking at fuel trims and O2 sensor activity.
How did you check for air leaks?
I would concentrate on finding out if there is an actual misfire or if you have a lean mixture.
Fuel pressure is also a point to look at.

The cars has been scanned with opcom, fuel trim looks ok, long term fuel trim is averaging about +3, just had it MOT'D a week ago, flew threw the emissions test, front lambda is up and down between 100 and 900mv with a average of 460mv over a 10 minute drive, i checked for leaks by spraying easy start round the inlet manifold, throttle body and the MAP sensor joint, no increase or decrease in revs was recorded,

The main problem is the car does it maybe once a month so really without having the laptop plugged in when i happens its hard to find anything, anything you could suggest would be helpfull,

" My model does not have a mass air flow meter, it has MAP sensor " that may be, but IF you posted the YEAR of the vehicle that would help.

Have you scanned all Modules, or are you only scanning the engine ECU, could there be a code in the cooling module.

A very BAD practice , the easy start can easily be ignited by a spark, also proves very little, a evaporative smoke test would be the way to test for leakage.

my appologies, thought it would be the engine code you required, its a 2001 zafira, ive scanned all modules, there was a code in the coolant module 00017 - no engine rpm signal - PRESENT, i started the car up and cleared the code and rescanned and it did not come back,

Yes i know the risks, i work with ether all day in my day job, the think i cannot get my head round is why will it run fine for so long before playing up, and why when it plays up does it correct itself so quickly, this is another reason why i think it may be electrical or something mechanical sticking, its never done it when the engines been cold, only hot,

I have had these errors in the past in the coolant module but they are not there at the min

00002 - Engine Coolant Temperature, Frequency Out Of Range
Not present

00163 - Engine Coolant Temperature, No Signal
Not present

You may know the "risks" but others reading your post may not ! ! !
