Check for vacuum hose leak like a hose that became disconnected, hose that is split, burnt a hole in, etc (or PCV valve failure). Indications are, will not run at idle, runs rough, the slower you go, the worse it runs. best of luck resolving this problem.

It's impossible for anyone here to give an estimate because rates and parts availability vary from state to state. I'd call your local Volvo dealer parts department to get an idea of the parts costs or even if they can find one. You may have a better chance of locating the parts in a junk yard.

What is wrong 95 BMW 318i starting issue and idle rough won't stat running?

Vane air flow (VAF) units are a common failure on these cars. It is the the sensor mounted inline on your intake tube that is aluminum and black plastic with a round twist plug. If you unplug it an it runs better that is most likely your culprit. The gentleman above is on the right track. Intake boot cracks/failures are quite common on these older cars too as are the EGR tubes/hoses - listen for air leaks/sucking noises.

The idle air sensor (IAC), made by Bosch looks like a small coke can with two tubes and a plug going to it. Sometimes they are hard to find/hidden under intake. They do go bad, but can usually be cleaned with car/brake cleaner. The internals should rotate; they are just an oscillating valve that regulates extra air to the intake.

You never said it it runs fine once it us up and going. If it does, it could also be a oxygen sensor. You should really consider having the codes read... it really shortens the list of parts to check!

Good luck!

Taurus running rough

Have you taken it back to the mechanic who replaced the head gaskets ??
If you have a second shop work on it you could void any warranties from the first shop.
If the first mechanic will not fix the rough idle I would look for a vac leak or a hose not connected.
