Ok at the moment the zook runs and drives. when driving at 100 kph in fifth gear there is no power when you put your foot down

The car does this in every gear and feels gutless as soon as its under load.

so far have had fuel system pressure checked
irridium plugh less than 5000km ago
air and fuel filters
all servicing up to date
new exhaust including the cat
both o2 sensors within the last 10000km
air filter

no check engine lights have come on

when one of the o2 sensors failed we disconnected it and ran the car with only one. it actually ran well then after replacing the failed o2 sensor it ran well then has progressivly gotten worse to the point its at now.

dont want to spend a shitload on chasing a problem. no one so far can actually tell me what is wrong or even how to test if somethin is wrong.

any help would be greatly appreciated

Dyno

engines dont need a lot to go, it will soon tell you whats going on then you can start to work out why

Any suggestions on a decent tuner???

[royce]

you dont need a decent tuner, just somebody can read the shit a scope reads out

AMMS or whatever they are called are at Sandgate, I spend a weekend drinking with one of the guys that runs the dyno and he seemed alright , hows that for a recommendation

Fantastic

never really thought to get this car dynoed. Will have a look at gettin someone a little closer to the southside

all a dyno does is gives you a way of loading up the engine without it moving along at 100km/hr, which then lets you hook stuff up to tell you if the mixture is ok, if the timing ir correct and so on, so you can spot a problem pretty quick

cant help but think the new 02 sensor thing is something unusual, has any gaskets been replaced before this all started?
