Haha, that's good because I know NOTHING. I'm one of these people that likes fast cars but doesn't know much about them unfortunately.
I asked my mate and he says he does recall setting the actuator up to the appropriate stock boost level but I've received ''Waste-gate Failed (Closed) errors on my OBDII and thought maybe the waste-gate is not opening because the actuator is set to open at 12psi but the stock boost is only like 5psi. Thanks for your explanation JETURBO.
I'll leave a short history of my car troubles below if anyone is willing (or bored enough) to have a read .
Car - 2005 BA MK II XR6 Turbo ute (230,000km)
I originally started experiencing boost cutout and rough idle about 10-12 months ago (the boost would cut and I'd hear a BRRR Sound until I took my foot off) so I took it to my mechanic mate who found a fault (waste-gate actuator) and he replaced it. The new actuator didn't fix the problem and my fuel consumption became really high with a strong smell of fuel. Since then I've also replaced....
- Solenoid
- Coils
- Spark Plugs
- o2 Sensor
- Fuel Pump (Most of the fuel smell went away after this)
- Cleaned fuel line
Fuel consumption still REALLY high (19.6L/100KM) and the car was running rich according to OBDII, at this point I replaced
- MAP sensor
- Injectors
- TPS Sensor
- Cleaned Throttle Body
After all this the car runs like crap, chews through petrol and the boost comes on ''inconsistently''. When floored from a standstill it will cutout but doesn't when I'm already moving. Previously I'd get errors saying the car was running RICH but now I get errors saying the car is running LEAN . I also have errors that indicate a possible vacuum/boost leak, I've sprayed soapy water (couldn't find anything) but was wondering if borrowing an air compressor and doing it that way might be the smarter way to go because I assume you need to simulate the actual boost going through the car like when you're moving.
I've been advised to take it to a tuner but from what I understand I'd be looking at $800+. The car is an 2005 model with 230,000km so at this point I don't think I want to be spending too much money on a car that's hardly worth anything to begin with.
