If you can... run it till the temp is up over 65-80ish C on the gage.

Thats when it should hold idle if the lambda system is working.

If you can get it to idle... get a 20$ multimeter (with a duty cycle setting is a plus) and you can use the links in my signature to read how the lambda system is functioning.

It will be a lot easier to troubleshoot if you can get it to idle.

For instance... if it gets better when it gets warmer you have a cold start problem...
