A legend bloke once told me not to bother removing the IACV to clean it...... because the screw head bolts are prone to stripping and you will most definitely need a new gasket. With a cold engine you can access the IACV from through the throttle body. Spray the shit out of it with UEC. Done.

Thanks for the link.

Spraying the shit out of it through the throttle body sounds like an easier option. Will do the easy way first.

Thanks guys :)

Cleaned the idle ACV, but today it still was lumpy on idle and it was spurting, lumpy driving at 60/70ks. And engine light flashes.

Could this be linked to a fuel filter/injectors? Or any other ideas. All vac lines have been replaced.

DPS hooked up correctly?
Trace the hose on the left side of the DPS, it should lead back to the intercooler. If it goes to the top of the SPV then it's hooked up incorrectly.

I'll suss out and map out if they are connected correctly.

Left side of dps goes back to intercooler and he right side goes to the spv... So all good by the looks of things.

Still no luck with this engine light and the car being very lumpy and unbearable to drive.It's all through the rev range now. Idle and driving.

I've cleaned the maf, changed all vac lines, cleaned idle cv, checked idle solenoid, done upper engine clean...

What the hell do I do now? New fuel filter? New maf? Injectors? I need help if anyone can point me in the right direction.

it sounds pretty fundamental - not a TT thing.

I'd be checking all the sparks are ok. Maybe one of your coilpacks has gone belly up or wiring gone bad.

If the idle is completely shite, then unplug them one at a time and see if one unplugs without changing the idle.

If no joy with that, pull the plugs and see if there's any evidence of fouling on any of them.

15 is Cam position sensor.
61 is rear O2 sensor.
168 is fuel temp too high????? Engine temp sensor?

If you are going to do it yourself... Get acces to a scanner. It will pin point the issue.

Alternately, do a thourough wiring & plug check, relpace the engine temp sensor, replace the rear 02 sensor.
In that order.

Get a mate with a scanner.

Cheers bosskong.

Fuel temp too high... Wtf???

I checked the fault codes and 61 says it's the inhalation valve solenoid or is it as you said the rear O2 sensor?

Trip to the mechanic with this one for the scanner.

Don't pay top dollar for the O2 sensor if that's what's needed.  Some of the lads here can point you in the cheapest direction.

I wouldn't think the temp sensor would be more than $30 -$40.  Disregard the code p0015 for now.

Think that's what will need to be done... Process of elimination and replace both sensors.

My mechanic is pretty good and doesn't charge to have a look.

Just suss out parts now

Where is the temp sensor located?
