forum.audiv8.com Foren English Audi V8 Forum Audi V8 in US help??? runs strange

Hello everyone.
I purchase a V8 in the US last year to bring over here to Luxembourg...thing is the car has a few problems I need to resolve before bringing it over.

First thing is I need to mention that I have already replaced all the plugs, wires, water pump, timing belt, ..basically the car had an extensive service last year.

The problem is..when I start the car..it starts well when cold but went it starts to warm up...takes only a few minutes..it starts running sporadic...as if not running on all cylinders.

My other problem also is I am not with the car right now..it is still in the US trying to get fixed and I have little trust in anyone torching these cars..so I cannot get anyone to check the fault codes which woudl be the easy way out.

Does anyone know what can cause this condition?
I need some ideas.....any idea ...will help.

thanks to all.

Howdy Paul,

ago two years i have had the akin problem with my 3.6 engine. When your car not runs on all cylinder´s you should check the runner inside the distributor and check the water Temp. Sensor on the backward side from the motor.

Florian,
thanks...I checked the distributor already so that one is out but the temp sensor is a good idea..i didn't think of that.

I will pass the information and keep the information here update how it goes...

if anyone esle has some tips ..please feel free to pass them over.

also you can plug out the wire of the Lambda sensor... to much gas ist maybe an Problem . you are shure that the rotation and zero-Point sensors are ok ??

whitch model and miles?? building??

frank,
it's a 1990 US model
3.6 (pt) with automatic.

Frank,
thanks, I will pass this information to the people on the car..
we had not checked all sensors yet.

Hi Paul,

are you aware of the US audi V8 mailing list? Perhaps somebody is in the near of your car and is able to come around and have a look. Some of the guys are extremely skilled!

Frank mentioned the engine speed sensor and the ignition point sensor - that's always a good point to start with. What about the intake air temperature sensor?

If you find somebody who is able to read out the fault codes he is probably also able to run a measure block diagnosis - this helps to find out of a sensor is providing wrong values.

Good luck!

Bastian

Thanks ...my English is not so fine...we must learn russian...

Hat doch gepasst! Wenn ich net die englische Version vom Vag-Com gesehen hätte, hätte ich auch nicht gewusst, wie die Dinger wirklich heißen. Ich hab' auch schon "Flywheel Sensor" gehört - von Native Speakern.
