VT Wagon 5.7 Feels A Bit Sluggish Kicking Down

[Thorby]

Hi All,

Just bought the wagon on the weekend, and after taking it on a 300km run it doesnt feel right. It has 217,000 on the clock and I bought it from the original owner and has a lot of service info that came with the car.

Crusing along and at idle all is fine, but try and kick it down a gear and it feels a bit sluggish. I have owned two 5.7's before one VT ex chaser and a VY manual SS that I bought new. This one has had the following done in the last 9 months.

2 x sets of plugs and leads.
2 x fuel filters.
2 x O2 Sensors.
1 x Airbag Module.
Several on car injector cleans.
2 x air fliters
2 x Decarbs

Plugs/leads/fule filter only 5 months old so where to next? I dont remember my VT ex chaser being this sluggish so your thoughts would be appreciated. I am now leaning towards coild packs but correct me if I am beeing a peanut.

Cheers

Anyone??? Any ideas?

Might be worth while investing in a scan tool.

Could be partially blocked catalytic converters?

Cats checked no drama, scan tool on no codes, brand new fuel pump today NO CHANGE.....time to put a rag in the fuel filler...light and walk away.

check your air intake, and maybe service the auto?

Compression test.

ok compression check was done, everything fine. Auto was serviced with complete flush two months ago. On scan tool yesterday, no faults logged. I am now leaning towards a fuel regulator or maybe suspect ecu.
