The engine management system may not be adjusting for the extra load of the A/C. Can also be the A/C compressor is seizing up. Have this looked at by a professional.
The car shakes because your engin has been cold and you sudenly start the car it will shake
spark plug gap Can also be a vacuum leak.
Simple, you ac does not blow cold air even though you have it turned on and the temperature set to cold.
yes they need turned or replaced, 65;
the engine mounts could be bad
Yes, when the engine heats up or the AC is turned on.
Usually when this happens to my car, its just because the RPM is lower than normal. Your car isn't warmed up (probably worse because it's getting cold out) and your AC is taking power that would go to your engine. This is what i have experienced with my car.
Check the alternator or the main lead of the ac wire to check for either if there is too much pressure is being applicated to the alternator or if theirs a shortage in the main lead wire to the ac
Normally this is caused by a warped rotor. Have your brakes inspected and rotors turned or replaced.
Check to see if the ac unit is spinning while the car is on and the ac is turned on. If it is not, you may have to replace your computer under the fan fliter. If it is, go out and get some ac dye to see if there is a leak in your ac hose
Yes they can. It can also be a vacuum leak, or defective idle control valve.
This is normal for most vehicles when the ac is turned on.
