I have had this car for 2 months now, there is a bit of a story to tell to get to my question.
Bought the car and the Trip Computer was telling me I was getting between 13-14.5L/100KM which was a bit surprising because all reports I read said 10-12, I am talking City Cycle. Anyway one day when the wife picked me up from the train station I smelt a really strong smell of petrol and I mean REALLy STRONG. I told her to turn the car off and get out. Called out roadside assistance and there was a fuel line just behine the engine if you go from the top, he just clipped it back in with a push, I heard it click. Since then no more fuel smell. I figured this may improve my economy now, WRONG! My fuel economy went to 16-17L/100KM consistantly.
I was very confused. Any way the spanner light came on when I started the car now but went out again. I took the car to a Holden dealer, they put the OP COM thing on and said yep your engine is missing. So they charged me $1000 and replaced the Coil Packs, $800 for the parts and $200 labour, yes I now know Holden Dealers suck. Anyway if I drive the car very gently now and peeve people off behind me I can get the economy down to 15L/100KM which still sucks.
Can anyone suggest to me what can be the issue? Can I use OP COM to adjust fuel mixture or something. I mean the car has only done 80,000 KM's, there is no smoke blowing and it runs quite well otherwise. I am lost to know and so was the dealer. Is this normal economy? if so I would never of bought it to be honest.
Any assistance would be appreciated.
