i hope somebody is out there that can help me, I just bought my vl bout a week ago and someone has screwed with the airflow meter but my car is hardly moving so im guessing i may need a new one so theres 2 questions:-

1. Can I Bypass the airflow somehow so that it runs just as good?
......OR......
2. How much will i likely end up paying for a second hand one?

p.s. thx for your help it will be greatly appriciated

check for spark. if there is no spark at all from the coil lead THEN it will be either the CAS or the coil. If you have spark then it will probably be the CAT (catalytic convertor). When the CAT is stuffed the mesh in side deteriorates and blocks the exhaust allowing the car to only go 20km/hr if you're lucky, even not go at all. The CAS is easy enough to do yourself and is about $70. There are a couple of kits available. Just the CAS or a kit with the dizzy bearing and electrical plug. Best to get the plug too, you can get it separately. To see if the bearing needs changing take the dizzy cap off and see if there is orange powder inside the dizzy. The powder is from the bearing being stuffed and kills the CAS.

still having the same prob guys, checked the dizzy and no powder at all seems to be fine, took exaugst off from just under the passanger door and no difference in the problem and the coil i dont even know where that is but as ive come to realise the problem more it seems to idle fine but whether ur in park neutral or a gear as soon as u touch the accelerator the car coughs and splutters and nearly stalls. How do u know if fuel pump is screwed? could it be fuel related and it seems that when u touch accelerator and keep it down a bit it sounds like its backfiring in the engine please help now im desperate and got the mc shits
