Few minor problems with 3.0Litre GTV6 Running 2.5 AFM

[turboalfa]

ok so ive finally got the car on the road for awhille and its been running fine apart a few facts which are starting to do my head in.

Now it blows smoke on take off and i do mean a fair bit. I also believe its because its running rich. Also it only really blows smoke if im idling for more then 30 seconds and give it a small shot u look in the mirror and the car behind has a mouth full of smoke. Most embarassing thing i reckon.

Now i can only use possibly a quater of the throttle . if i use more it will start to cough and run like a pig.

im not sure if updating to a bigger AFM will fix all these problems. also does any1 have an ecu hanging around i could buy cheap by any chance. i just wanna get it running a bit better so doesnt need to be top of the range its just so i can eliminate the AFM and do it all my self.( fuel and air mixture)

You could try tightening the spring inside the airflow meter. Idealy you would use a wideband air/fue ratio meter to make sure you aren't making it run to lean. It does sound like you're a fair way from that.

Failing that, try and get your hands on the 3 litre computer and airflow meter. Tho I have read the the AFMs are the same size, the resistance characteristic of the wiper may be different.

Have you checked your fuel pump?

fuel pump is running fine. i still think when i apply to much throttle it coughs a because to much fuel not enough air vice versa. would this make sence?
