Why wont my VT go hard when I accelerate??

[Ozzie]

To cut a long story short....

The running gears all done 270,000.
The only problems ive had is with the transmission cooler blowing but i seemed to have fixed it.....


The other day a mate drove it.... (She ownes a VT II Olympic edition)
And she mentioned that when she put her foot down a little bit, it was sluggish. and i mean sluggish (I have noticed this since I bought the car)

She says that in her VT, when she puts her foot down a little bit it just wants to GOOOOOOOOOOO>>>>..

Any suggestions on what could be the problem?

Cheers for any helpful info guys:thumbsup:

blocked fuel filter.....spark plugs/leads....low fuel pressure....blocked air filter.....slipping auto trans....allot of things can cause this. Also could be that there is not allot of compression.

id start with the fuel filter and plugs/leads air filter

Fitted new fuel filter, new leads & plugs, fuel preasure is good, its a new hi-flow filter.

Slipping transmission might be something to do with it.

One thing i know is that in 2nd or 3rd @ about 3000rpm it wants to just go>>
But from 1st to 2nd its as slow as a combie van with my foot flat.

When I had a VT V6, and I did my O2 sensors, the responsiveness picked up A LOT (and about 2L/100 better fuel economy )

Ecotec never had super low-end torque, but should be better than what you're describing.

Also recommend a MAF clean, helps a little with response too, especially if you have a oiled air filter, they get dirty pretty quick.

Must say that my stocky 6 doesn't sparkle off the mark either, tho it has never bothered me. At around the 3000 mark, it starts to noticably have a surge in power.

same here, VT as well

diagnosis would be its a v6...

knock sensors?

lol was thinking the same, my vt is the same so i gave it to the missus cos i couldnt stand how slow the v6 is

Now on the other hand, the family Magna V6 powers of the mark, would 'eat up' the commy, very sensitive throttle, easily smokes the tires.
