SOURCE: Engine shutter and lack of power

You probably have a vacuum leak somewhere. Check for broken or cracked hoses and/or plastic pieces they connect to. Pay special attention to suction pump, part# 058 133 753 B. Google it.

It can be a problem that is simple to complex. Best see a mechanic for a personal inspection and recommendation.

Audi A3 2.0TDi Sport 2006 runs fine on idle when cold but has a slight misfire when hot, I have changed the fuel, air and oil filters, where should I look next?

Diesels can idle rough, if no check engine light I wouldn't worry. Check the injectors, vw diesels have the injectors work loose allot

Chevrolet 4.3 V-6 sudden lost of power.

That means it has a miss. Either you need new spark plugs, wires, or a bad coil. Make sure all the spark plug wires are on all the way.

My 2002 a-6 3.0 suddenly started running rough-engine light is on and blinks at 45mph. runs doggedly

Check oil and coolant levels (at the radiator cap) first. Run fault codes to find which sensor triggered the engine light . The light is to tell you that the engine is in danger of failure so do not dismiss the light as not important.. Hot smells mean that the engine is very hot and you may not have any coolant in the system to activate the temp light or gauge.

A year ago my 2008 Audi a4 developed a rough idle and loud engine no check engine light call my dealer they performed fuel pressure switch recall intake manifold secondary throttle body recall two months...

what A4, lots made.
see here for list

it's a complex car, all are ofter 2007 and for sure Turbo's
as such can be very hard to work on , and diagnose.
noise and rough idle.
noise is a hands on deal, no net bunny here can guess. that.
but rough idle
that is called misfire.
if a diesel misfires , we check compression first.
the injection rates.
some times just looking at live SCAN data you can see a problem.
my advice find a good German mechanic.
no country stated, making all answer near useless. (oh shock of that)
in my shop i can see you, the car, and the tavern across the street
called Nunavut nook.
a clue. there.huh?
in USA Audio or any ASE certified shop.
or if USA< try alldata dot com.

I started my 2006 chevy cobalt this morning and it idles really rough and my check engine light is blinking on and off. It ran fine the other day when i drove it

Rough idle, flashing CEL, low power would indicate a faulty ignition coil. A armchair diagnosis would be to replace the ignition coil. You'll have to swap the the contact stems (rubber conductors between the coils and the spark plugs) and the igniter module.

Simple task requiring a 10 mm socket and ratchet, a 10mm box end wrench, a T-15 torx bit with adapter and a new coil pack. Cost around $100 and takes a half-hour.
