vs supercharger running real ruff..

[mz-v6-2c]

ok so i just got my car back a few weeks ago from getting my heads re done, now since i have had it back i have noticed the car is chewing a hole heap of petrol, outa of a full tank im lucky to get 160k's if that .. when i got the car back i noticed it idling real ruff after about 1 min of turning the engine over, and the idle gets to a point where is sounds so sick and is bout to stall,but once the aircon is switched on the idle changes again and seems to idle ok, then once driving i can hear a whole heap of air coming from to me sounds like the vacuum hose or around that area.also when it does seem to run like this it is almost like it is not getting enough air flow and its causing the temp to jump real quick. i have recently replaced (brand new parts ) the crank angle sensor, the water flow sensor (if i named that correct) the coolant sensor, the air flow sensor/meter, radiator, water pump, fully serviced with plugs, leads, fillter etc, thermostat, fuel pump ( that part is second hand) battery, thats about all i can recall at the moment, but honestly, my mechanic did stop past tonight and told me that he "thinks" it could be the 2 sensors near the throttel body near the cold air intake up the top , not to sure on those two sensors are called, and he himself said that he has never changed these parts before? has anyone been thru a similar thing on their car like this that can maybe help me?

The two sensors on the Throttle Body are the Idle Air Control (IAC) and the Throttle Position Sensor (TPS) both are fairly common faults. The IAC controls the air-flow at idle, I would change that first. The TPS senses how far open the throttle body's butterfly is.

if the Throttle Body are the Idle Air Control (IAC) vacuum line comes loose it will run like balls. Mine comes loose every now and then and it barely turns over. Looks like the engine is about to jump out of the bay as well.

The line is directly under the TB. On mine it has a 90 degree elbow from the join to the line.

If you had the headgasket done and its eatting a shit lot of fuel, it sounds like the o2 sensor is cover in silcone/silastic etc etc . But the best thing to do is to put a scan tool on it and see what codes comes up...

yeah im going to get it checked at 6pm tonight, and run the scanner over it... i hope it shows me the right error ... when you said the lines could be lose, where exactly are the correct lines, are they the ones where my mechanic actully point too me right up the top of the throttle body? as for the cars performance ha, the car is dead... its got a bad flat spot at the start of the excellration, and finds it really hard to kick the engine over? so im guessing it could be what you guys and my mechaic has suggested? does anyone know the ruff price on these 2 parts?

I will sell you a vs v6 throttle body complete with all sensors ($20 plus postage).... NOTE standard v6 are the same a super 6 throttle body

sounds like you have a air leak and i would check the iac valve that could be the reason your going though alot of fuel

well i got the computor scanned and the electrician told me the error it read was tbs .. .. .. ahh also told me that my leads were sparking (3) and needed to be changed... i dont understand that cause my leads are brand new but ah well i changed the leads again today and for bout 5 mins it made a difference but then it went back to the way it was.. so now im up for the throttle body senor i think its called and ive been quoted around 100.00 ... but if i was to change this as well will it make a difference in my fuel i am using? cause seriously i put brand new leads today and put 20 dollars petrol just to test it to see if that was why i was usng so much fuel and i only got 45 k's out of it and that is with my petrol warning light on .....
bti-355 how much are you asking for that? cause i just may buy it off ya hey, if u can inbox me, are you located in nsw or?
dannyn12, when u say air leak i thought the exact same thing! cause that is all u can hear at the first 60k/m of acceleration ... is there a way i can check this?

[mz-v6-2c]

also im noticeing the temp going up to 3 quators? is that normal to with the throttle body sensor screwed? cause seriosuly i just got my heads done and i am really preying that my fuel consumption and the temp all comes under the one problem other wise it just means more cash and i really have spent more then enough on it in the last few weeks thankyou so much for ya help guys,

Did you fit the heads or the mechanic? If he fitted them, then it's his problem to fix. Alot of people make simple mistakes when fitting heads to super6s. Ask the mech if he used thread sealant on the head bolts for one. The head bolts go into the coolant galleries and it would act like a blown head gasket if not done properly.

Also there are some vacuum hose that are complex to configure and are easily misplaced. Get you mechanic to contact Holden and get a vac hose layout diagram for the vac lines especially the purge solenoid cross pipe at the rear of the engine. There is also the boost bypass solenoid that's easy to mess up so all of these need to be checked.

If these are all proven to be correctly configured then I'm afraid it will be a mechanical issue. TPS doesn't cause the problems you are talking off usually. A TPS fault will give DTC21 and also a coolant temp sensor fault too because they run off the same earth on the super6

ahh one new thing i have noticed today is that when they have taken my heads off the car and gear box to replace the wear plate, grr it looks like they havnt put my exhaust on properly... ahh i seem to have no luck with these mechanics.. mind you this is the 3rd different one i have been to now...
chrged vx6 yes it was done alll by mechanic... he took heads off, then took the heads to a place called "raceteck" they fixed the heads and he put them back on... i will be returning the car to him tomorow to get him to repair all hes screw ups now... will let ya no and il ask him all those questions and see what he has to say bout it.. thanks heapz
