1987 Volvo 780 idle problems??????
Everytime I start my car for the first time in the morning it runs rough like only firing on a couple of cyl. I end up having to hold the gas down for about a minute for it to clear out and run half way smooth. I need all you volvo guys to help me out with this. Im new to volvos so any info is appreciated. thanks. oh and its the V6. thanks
Could be alot of things. Has the car had a tune-up recently? How about a new fuel filter? Perhaps the throttle body or the idle air controller needs to be cleaned. Could also be a vacuum leak. Maintenance is key.

well..my temp. gauge just stoped working. would that make it run rough??
When I get to around 3000rpms the car goes flat on its face and then keeps going for a slight second.
well that car doesnt have a thermal time switch only the earlier v6 models. This is all electronic injection. I would say most of the time on cold starts it it the coolant sensor. Also it could be a bad distributer cap especially if it is anything other than a bosch, volvo's hate cheap caps and run terrible. Now it also could be about a dozen other things aswell hard to say with out looking. If you ever need a mechanic we work on alot of volvo from all over hampton roads. I have 1 from over your way in hampton here now. Anyway pm me and I will give you our number if you want to drop it off for repair. Goodluck
