Hi guys, I need some help here got a similar problem but not exactly the same!
I have a 3.0 litre GTV 2001, its has a re-map and Carbon Dynamics Induction Box/Filter. Apart from a slightly lumpy idle, it has been running well with masses of power, up until a few weeks ago at which point it literally felt like it had lost around 50 BHP.
Its not running particularly rough and doesn't hit a brick wall with a sudden loss in power in a specific part of the rev range, it feels like it has lost power over the whole range and its instant throttle response and free revving has turned into a flat gradual increase.
I noticed the Air flow pipe (with the resonator boxes on it) had small splits in it and after a few days of hunting around with no luck to find a decent replacement I bit the bullet and purchased a brand new unit (ouch...)
Fitted it with high hopes but she's still running flat as a pancake...A lot of things point to MAF but just wanted to be sure before shelling out more money, could it be anything else??
Is it worth disconnecting as people have suggested and if it runs fine then its the MAF? Also if I've had a remap would an ECU reset be suitable or not needed?
Lastly is the Vauxhall MAF posted here by GTV blue exactly the same unit or just the same sensor?
Any advice would be appreciated.
