R33 Dying...help...please

[fletch63]

Hi all

My beloved R33 is dying

It started to lose power on boost a few days ago.

Today it got worse real quick

It started to hesitate and had no torque at all

It was harder to keep idling and started to get harder to drive

It sounded like it was sucking heaps of air and was backfiring

No power on the way home from work

no acceleration at all

!00KM/H on freeway took about a 10KM runnup it was running so bad

Hills are 10km/h

The first warning lamp came on (CAT temp)

Now I have it home it sounds like a truck when I start it up and struggle to keep idling

I have reset ECU Will now look at how to put it into diag mode

I have also jacked it up and considering taking off the CAT and having a look

Any help　would be appreciated heaps

check for air leaks in the intake piping

[snozzle]

is it throwing smoke? if so is it black? white? white/blue?

no smoke only a little bit of black smoke on backfire

[fletch63]

Ok now i've put the kids to bed I've looked at the ecu and can't see where the screw is to turn in on to diag mode

I am working in low light

Ihave checked for air leaks and all OK

Can any one tell me where the screw is for a single LED ECU

Cheers

wait a minute

after close look I can't see any LED or screw

I will plug back in and see id it works like a no LED ECU and shows up on the dashboard

fuel pump is an in tank one and you can hear it prime up when you turn it on

I thought of disconnecting AFM but couldn't even get the plug off

HELP!!

The ECU diags was a dead end

I plugged in the ECU and turned the key and the engine check light came on as did all the others???????

HELP!!!!!

[JonnoHR31]

check for air leaks again.

if your absolutely 100% certain there are none then check fuel pressure

[livicuru]

Check all intercooler piping / hoses for leaks!

Thanks man appreciate your help

I am in Woodvale

I don't think I can drive my car

It is running really rough

It won't idle, It accelerates real slow so traffic builds up behind me

I can just crawl uphills

It seems like it can't get any fuel

So Im about to check the filter

Id like to then check fuel pressure but how???

I know it sounds like an air leak but I can't find any

Sounds like a truck with no exhaust and suckind lots of air sound

Get it towed to the closest workshop, don't drive it you'll just make it worse.

Blocked cat maybe

[fletch63]

Taking the wifes galant to work...NOOOOO

Anyone know a place close to Woodvale that won't rip me off

Also will attempt to take the CAT off tonight

After all the CAT temp light did come on for a while

Check fuel, air and spark. Doubt it's spark, but check fuel and air. Sounds like it's misfiring badly, so it's not a good idea to be driving it around. If you can't find anything yourself, tow it to a mechanic.

Hi all,

The latest news is that I got the no LED ECU to go into diag mode and it all came up good (55)

I then had good look underneath and found there was a nut missing where the turbo bolts onto the front pipe.

Because this is where the loud noise seems to be coming from and the symptoms seem to agree maybe its just that

But there are no signs of a leak and it all looks tight and flush (held in with other 3 nuts)

What do you guys think???

Ahhh the reason i love BMW's so much. They just don't go wrong.

Problem after problem with the Skylines =\ (no offence intended).

YEAH MAYBE BUT I CANT FIND ONE

SOUNDS REALLY LOUD AROUND THE TURBO/EXHAUST AREA

MOTOR SOUNDS OK BUT HARD TO KEEP IDLING AND NO POWER AT ALL

THE ONLY WAY TO BE SURE I SUPPOSE IS TO TAKE EVERY HOSE OFF 1 BY 1 AND INSPECT IT

ANY IDEAS WHICH WOULD BE THE BEST WAY TO APPROACH...ANY COMMON ONES ETC

ANY ADVICE WOULD BE MUCH APPRECIATED

The leak will most likely be in the least accessible place possible, it's Murphy's Law

I have taken your initial advice

booked into Hyperdrive on Saturday and yes I will have it towed

Andrew was very helpful

I think its either an air leak or turbo gasket

hope no more damage

Thanks for your advice
