problems with VK EFI

ok heres my current situation, ive had my 1985 EFI VK for about a year now and ive had serviced twice and had to have the camshaft gears replaced as well, the main problem is that when i start her up she blows a bluey grey smoke cloud, which may i say really impress the boys and the ladies, to go with that she has a really rough idle it seems to have trouble either breathing or getting fuel as the revs are all over the place and after a while the rev difference gets so much it stalls the only way to fix this is to boot the accelerator when it starts to die. plus it will sometimes stall when going from drive to reverse when its just started up. does anyone have any ideas, i would like to know wether to trouble shoot this now as im looking at upgrading the exhaust system and chaning it from an auto to an manual, is it worth the trouble shooting or should i put up with it for now and get it all rebuilt later?
thanks

mate sounds to me like your engine is not in the best of health. Firstly, the blue smoke means oil is burning, i'd say it would probably puff some smoke when you rev it aswell, and even when you accelerate under load. If the engine is low on power/ using oil and maybe not getting as good fuel economy as it should, i would definately think the engine needs a rebuild. As you've said the timing gear has been replaced, to me this would indicate a engine thats pretty old and the gears just had enough. I bought a efi vk a while back and it used to idle crap and die in gear when cold like you've just said, when i got it home i poped the bonnet and had a tinker with the air flow meter and it idled sweet as .... so that was a mixture problem. (to rich i think from memory) either way, i would put off the exhaust and speak to a mechanic and find out if the engine is shagged. Compression tests, and other checks will soon tell you the engine life is getting low.

what exactly did you do to your air flow meter as i have a friend who is a mechanic coming out hopefully this weekend to do some tests on it and asked me to ask you what you did. and i think it will need a rebuild as the power is lacking but im not too sure on the economy, the main way i know the power is shot is that my coaches son has the same engine as me in his vh and it eats mine alive. and i only plan on getting the exhuast if it needs a rebuild, as id like to change it over to a manual, most likely a celica setup (any information on this would be highly appreciated) similar to your vk setup on your website basically get it all done at once so as there isnt as much fiddling around

mate firstly, what you have to do is remove the black cap on the air flow meter (sealed with selastic) then inside this is a little wheel with teeth on it .... it has a little bit of metal acting on it as a spring to stop it from rotating. Please note, if you lift the metal away from it, you can expect it to move and most probably stuff the time of the car, so make sure you hold the wheel when lifting the metal away from it. Anyways you have to turn the clockwise to lean the car and anti-clockwise to richen it up .... then once its better from that, there is a little hole in the front top of the air flow meter with either a flat screw or allan key hole, it is the fine tuning, you can use that to get it perfect. If you can understand this and know how to tune a car then you should have no problems.

as for the celica, i can't suggest the issues with a conversion to a commodore, but i would advise you to ring dellow automotive in sydney, or www.rodshop.com.au and they should be able to tell you everything you need to know about the conversion. I got mine from dellow.
