Well,have i got a lemon or what,after the radiator issues,im now on to issue 2,or 3....I will refresh myself here,i purchased this 89 vn few weeks back,all was good there for a while,until it stalled in my driveway,then would not start,i did manage to get it started by holding accelarator flat to floor,then she fired,she was coughing and spluttering,plenty black smoke(fuel) out of exhaust....Then since then,this has happend a few times more,to the stage now,it stopped in traffic,and made me feel red faced a few days ago,to the point,i was tellin the missus its a lemon,and its goin,but she loves it,and,well,maybe someday i might start to again.....
This stallin thing only seems to happen in first 5 klm of driving,or if i start it in mornings,as it seems to occur when engine is cold,and let idle for few minutes,when i go to take off,she stalls,then has trouble starting,and flat to floor with pedal,and she starts,cough,cough,plenty black smoke,and away i go...
After a few klm,shes right for rest off day,im thinking the automatic choke is stiking,and is flooding the car,do they have a auto choke,but its only when its first started all this flooding seems to happen,mind you,she starts first go,but after few minutes of idling,or if i drive away straight away,and i get to traffic lights,or stop sign,she stalls,and what ive explaqined,happens again,hard to start,and plenty of black smoke,then after i get going again,shes fine,until next morning......Do you guys think this is a choke issue,or something else....??????
Cheers........

Most commodore owner go through this stage, i suggest take a break, wash the car and identify every fault you wish to fix. Then complete a major service, oil, filters, plugs,leads, sensors, clean throttle body & iac out, reset ecu, etc then you will have a starting point.
I think a major service and replacing engine sensors may do the trick, but you never know on a car that hasnt had tlc for a while.
whats its history, km's etc..

The symbol that has been coming up on my dash board what im thinking is the overheating symbol,is the same symbol that flashes when i did the fault test earlier, and came back as code 42,is this symbol ive been thinking the overheating symbol,or is it the computer symbol...Its the closest one to my left hand indicator light on dash..Any way,should i do a reset of the computer, and then go do another computer test,before i go and buy new coil pack,as ive only had the car few weeks,and been thinking maybe previous owner has not reset the computer,and nothing wrong with coil pack.....I hope someone can shed some light on the symbol thing,and have i been thinking the overheating symbol is not that,but something else......
Cheers.... |

the symbol you are referring to is the check engine symbol....i think the only time the vn was fitted with a overheating symbol was in the calais ...but it would be on the right (i think)

Hmmmmmmmm,ok,i did the code test last night,showed up era 42,i thought i would reset the computer thingo today by removing the 2 fueses as stated in a post here,then check the code errors again...
Well,now after doin the reseting,car seems to be running slower at idle,and now the code test is telling me its number 12....Yeee,12 is that i have a perfectly good running vehicle,maybe ive bought a apple,and not a lemon,fingers crossed,as im about to go do road test....
Stay tuned for update........

Alright,you guys have been waiting for the road test result,well,it was looking it was not going to get out of the garage....Did not get time to road test it yesterday,so out of bed earlier today,into the garage,and this is the progress....
Remeber i reset the computer thingo on sunday morning,and then re did the code thingo,and it came up as number 12 (12 is saying my motor is sweet)Sat night before reseting computer,came up as 42...
Well,turn of the key today,fingers crossed,she started first go,as usual,was idling ok at first,then she started to idle a little faster,and faster,and faster,until she was happy to idle around 1500 to 2000rpm.....So i gave her a quick pump of the accelarator,after about 3 minutes of starting,then,yep,you guessed it,cough,cough,splutter,splutter,stawell.....During this process of coughing,the orange light appeard on dash,what the f,after it stalled,i did the code test,came back as 42,just like it was showing sat night,before i reset the computer.Grrrrrrr,turn key,motor just turning over,not even sounding like she wants to fire,so flat to floor with accelarator,and she fires up,runnin like a dog,black smoke as usual,cough,cough,splatter splatter,then after a few seconds,stalls..........Then repeat process again,flat to floor,she fires,cough,cough,plenty black smoke,then she clears after about 30 seconds of spluttering as im pumpin the pedal........After she clears her self,she starts to idle bit slower,and shes ready to go,after this,i drove around for about 1 hour,stopping at the bank,shops,driving to supermarket,came home,back out again,and not a problem,she ran beautifull,even managed to get her a bit sideways in the wet........So Im believing this must be a fuel problem,correct me if im wrong,but do these things have a automatic choke,as by my experience with cars,it sounds very much like the choke is stiking on,and flooding vehicle,im no mechanic,but seems to be pointing me in that direction,throttle body was cleaned out with the nulon i was reccomended by nadg,so what next.....DO I GEET A MATCH,AND SET HER ALIGHT,GRRRRRRR........
I have it booked into a mechanic friday,so until then,im open for ideas.....P.S. I won the ceptor rims on ebay,there sitting in my garage ready for painting...
Cheers....... |

Just break it down into little, more manageable jobs mate. I can say that without exception everyone here has atleast a handful of things they'd either need to do or like to do to their cars.
Fuel pump, fuel regulator or leaky injectors maybe? I don't know much about the fuel system and think that's pretty much everything! They don't have an auto choke as such but the computer compensates fuel flow to get it running as best it can. |

| yeah if your thermostat is stuck open then the comp will give more fuel as it thinks the engine is cold - which would explain why you might assume it is an auto choke. i would say this is the first thing i would do - won't fix the major problems but its an easy start and should make an improvement and less symptoms makes diagnosing other issues less confusing |

| also - just a guess but the black smoke *could* be caused by carbon build up in the throttle body - give that a good cleanout and see if that works. If its really bad that could be causiing it to stall as well |

Well,problem solved,aparently code 42 was leading me to coil area etc,or somewhere down that line.......Turned out to be the coolant sensor,a quick look and test by the auto elec,and bingo,problem fixed..Even have got rid of the flat spot she had too........
All systems go now,and looks like im a proud vn owner again....
Getting me new ceptor wheels fitted tommorow........
Will post some pics,over weekend.......
