1979 Volvo 264 2.66 liter V6 idle problem
I have a 1979 Volvo 264 that won't stay idling. When started cold it will idle well at about 900 RPM for about 30 seconds and then it starts to fall in RPM, goes back up, falls even more, goes back up less, etc until it dies. If i try to start it up again without waiting a while it picks up where it left off and goes up and down until dying, instead of idling well for a little bit like when started cold.
It accelerates beautifully. I drove it around the block to warm it up and it does not hesitate to accelerate or bog at all, but when stopping to turn it was extremely close to dying at idle.
For what it's worth, it is fuel injected. Also, I'm waiting for a service manual to come so I'm unsure of the exact anatomy of the car, although I have the owner's manual which is somewhat useful.
