Hi all, any help would be really appreciated.
Firstly: My head gasket blew a few months ago and ever since it has been fixed, i can smell petrol fumes (only when engine is cold) in the cabin. This NEVER used to happen. Any idea???
Secondly: I have a sneaky feeling that my trip computer (distance to empty) is lying to me. I have 48L of fuel in the tank, i am averaging 11L/100Km says the trip BUT it says that i only have 280Km till empty...hmmm, strange no? Currently my distance to empty calibration is set at 499? is that factory?? Whats your setting??
Finally: I am having a weird issues recently where very occasionally the engine seems to run on only 5 cyl. When it happens its like it backfires slighty and stalls and then i cant start it. Its very rare that it happens, but i hate having my car unreliable. Also just yesterday i noticed that when i took a uturn real quick, the engine power cut until basically there was no body roll and i straightened. Now i have already replaced the fuel pump and the leads/sparkies/DFI and coil pack are all relatively new... so anyone got any ideas??? OH and i tested the diagnostics with the cable and the flashing engine light and it says all satisfactory!
Until now, i have NEVER had any issues with my calais and I look after it well so you can understand my frustration.
Cheers Patto

hi there Q1 well the petrol fumes might be coming from the fuel line to the injection rail or the return line Q2 i have know idea as i don't have a Calais Q3 well it sounds to me that your cas might be dieing. now when your turning and the motor looses power i use to have this problem when the fule gage was at the quater of a tank mark what i found was the return hose had come off (IN) the fuel tank, i found this out after my fuel pump died and i puled the tank out to clean it now the hose (IN) the tank from what i can see returns the fuel to the reserve part of the tank where the fuel pump sucks from and when you turn corners the fuel stays in this little reserve part but if the hose has come off the fuel goes back into the tank any where so when you turn the fuel runs to the side of the tank and the pump **** suck it up, this will end up burning your fuel pump out so look into it to save some money in the long run, now i was lucky to have a 8year old daughter that can fit here hand and arm into the hole and put the hose back on and a real long screw driver to tighten the clamp all fixed now it never gets that loss of fuel when turning hope this helps

Thanks swiftone...
For the fuel smell, i have inspected (as best i can) the fuel lines and injector rails but they all appear to be fine, i might have a good look at the exhaust as well although i shouldnt have a problem with it.
With the loss of power, i'll take a look when i am low on fuel again (saves me sucking out the fuel) and pop out the fuel pump, see if i can see anything. I was also thinking that i could be the crank angle sensor going so i might have a fiddle with that too and see if i can cause the fault. Although, i think its behind the harmonic balancer so it will be a poo to replace.

The CAS is a poo job to do. But typically if it's on it's way out the entire engine will cut out, not just one cylinder.
Check the condition of the leads/plugs/coil-packs. Yeah, I know you just replaced them all, but they can die at any time.
As for the fuel usage/D.T.E. figures: do you know that there's 48L in the tank because that's what you put in there, or because that's what the cluster tells you? If it's because you know you put in 48L then it's quite simple. The fuel gauge under-reads. That is, it says that there is less fuel in there than there really is, so by the sounds of it it's saying there is only about 26L in there, instead of the full 48L.
Mine is out by about that much, when my gauge says empty I know I've still got about 20L in there. It sucks but it's the way it it, you might be able to re-cal the cluster, but I'm not sure how to do it. |

Cheers mouce... Yeah one thing i noticed (only happened once so far) is that when i did a tight and fast u-turn, the engine did in fact cut out. It didnt stall, just cut all power and once i was straight again all power returned. Thats what made me thing CAS.
I have rechecked the sparkies and leads, i'll have to take a look at the coil pack one the weekend when i get time.
Ok, i will admit that when i quoted that 48L, it was what the cluster was telling me... in saying that though, i know this morning i put 55L in the tank and the cluster told me there was about 55L in it - so i assume the cluster was correct before. Do you really think that the gauge could be 20L out? Thats like 1/4 of a tank!! For me, i mainly notice that when my gauge says its empty, i have about 5-10L MAX remaining in the tank.
Oh and i still can not find the source of the petrol fumes in the cabin - its really sh**ting me off!
I'll update if i find anything - cheers |

I know you can get the gauges recalibrated (but to the best of my knowledge you need to take it to an Auto Elec to get it done), and if you've changed the fuel sender you'll need to get the dash calibrated for the new sender. I had a similar problem with a Kingswood I had, the gauge was accurate till the sender shat itself, replaced the sender and the gauge always read 1/4 tank over what was in there. |
Don't mind me, Ive heard a lot, seen a bit, done some of it . That and Im probably not quite sober. |

| It might be common knowledge, but the number of times you hear/see that question asked you would think otherwise.... |
