Need Help Quick

[ztuned]

hey guys,

i'm taking the car to the mech tomorrow morning. but just need some ideas quick

Took off to go to work bout 6pm, car is still warm as i only got home at 5.30pm, so no need to warm up the car

come out of my driveway, probably hitting 3000rpm ish, car goes POOOOP, i was like wtf. Then power starts cutting out(lights start dimming and going bright again), eventually the car stablises, idles at 1000rpm, then alll of a sudden the revs build up slowly.....from 1000rpm to 5000rpm. so i turn off the car

so i opened the bonnet to make sure my accelerator cable wasn't caught. everything looks fine.

turn the car on, car revs slowly up to 4000rpm again~!!!

then i turn it off, stepped on the throttle again.

and turned the car on again, this time it idled properly. at 800rpm ish.

so i put the car back in the garage, and go to work as i'm alrdy late.

come back 4hrs later

turn on the car, idles properly, so i tried to back it out. i reversed about 5metres, car starts acting weir again. i let it idle, and it idles hell rough with revs jumping up and down ( 800-1000rpm). and the car sounds like a rex

so i wait for 2 mins witht he car on, then the car idles normal again.

tried to take it for a drive. the car feels hell weird, no power at all. so i tried to slowly boost it..but NO boost..wtf..i can hear the turbo spinning making a weird sound...

then the car starts losing power again. it struggles to idles. then stallls...wtf

i can still turn the car on, but idles hell weird. doesnt have power at all and doesnt make any boost

so any suggestions? please, i need to know whats wrong lol. or i cant sleep tonight

coilpack? turbo? cylinder?

and btw lately when i take off slowly i can hear a very light 'hummming' noise from the engine, but never took notice of it

so any suggestions plz/??

cheers

sorry bout the long post, and it probably doesnt make sense.

mate check all your inter cooler pipes and silicon hoses

Sounds like one may of come off when you where boosting

just a suggestion

I checked just then, but ill check again in the morning

cheers

Wont be a cooler pipe,car wont rev at all if it was.

Do you have a PFC with hand controller? If you do check out the sensors to see if any are blacked out.

Your tuner will be able to diagnose it though.

Good luck with it all

dont have a power fc, just a SAFC

Sounds like you have shit a turbo. Comp wheel comes off, fragments move through the intake, get caught in the t/body and hold it open. Then, said fragments move further in to the engine and cause more havoc and damage as the engine tries to digest them.

Might not be your problem but is still likely and no-one has suggested it yet.

[The Dan]

Take the pipe off the front of the turbo and make sure all the blades etc. are still intact.

sounds like it is a turbo problem, if it was a cooler pipe it probably wouldnt hold idle, you have to have your foot on a bit to keep it alive.

start by openig the bonnet and pumping the accelerator and watch the throttle to see if its moving smoothly/correctly. since you mention it sounds like a rex, i assume its not firing properly and you are looking at either fouled/damaged plugs or inaccurate fueling. check all the wiring from your safc to the stock ecu harness, if you've damaged or d/c one its an interesting cause to the problem. could always remove the safc for troubleshooting anyway.

because it revs out, we can assume that its not in too bad a shape or it would have detonated. i would say the stock ecu is doing its best not to have the engine shit itself one way or another.

i would suggest check all the pipes tho, as its the easiest to fix, then im afraid you may have to dig your way in to the turbo and check it.

yeh found out it's the turbo that's gone. i'm gonna have to drive it like twice a week for the next month before i can get a new turbo

am i surpose to remove the dump pipe and and pipe from the front of the turbo to make sure the blades and seal arent just sitting there?

[tacker]

that would lead to more problems i would think
