My car makes fluttering noise when starting cold

This could be a serious problem for your car. You should get it looked at immediately in my opinion.

sounds like a timing belt or cam issue. The noise is the sound of valves opening and closing at the wrong time. Do a compression check.

check for vacuum leaks, also brakes can cause a chirping sound if worn to point or replacemen

Sounds like the blower motor...at low speed it makes the noise due to motor or blower wheel out of balance or something in the blower housing

a release bearing will make noise when you push on the clutch, the input shaft bearing will make noise when you release the clutch, the transmission will have to be removed and torn down to replace the bearing.

The actuator is causing the fluttering. When they are starting to go out, the locks will flutter. It seems to have more problems in the cold, because the lubrication in the actuator gets thick when it is cold.

There are 2 things that cause the tach to do this, one is the tach itself has a problem or a connection to it, the other is a leaky plug wire, it sends out radio noise, the tach picks it up and the needle spikes up and down, saw it more than once, sold a customer a tach and it was a bad plug wire.

I believe you may be referring to 'pinging', Try a tank of premium gas and see if it stops. Check your timing, and when was it last tuned? Let me know what u find. countrycurt0

I WENT TO THE VW DEALER...HAPPENED TO PASS BY. THE PROBLEM WAS SOLVED WHICH WAS FLUTTERING SOUND FROM THE AIR CONDITIONING FAN.

IT WAS COMING, I WAS TOLD, FROM THE MECHANISM THAT ADJUST THE TEMPERATURE, AND NOT THE FAN

THANKS FOR THE FOLLOW UP

I just repaired my 02 Galant with same problem. I removed the heater control box and disassembled and applied 12 volts dc and verified motor was ok. Then attached the plug back on and checked in car still not moving. Removed the screw holding the temp. control and cleaned contacts and applied pro-gold contact cleaner and preserve re-assembled and heater works like a chame. Saved 400-500 bucks and we have heat. About 2 hours labor to remove bottom part of dash and troubleshoot.
