When i drive the car with or without a/c the vehicle shakes
Expert:  Sparkybuoy replied 10 years ago.

When you turn the air on, does the engine speed increase, especially according to the tachometer?

Reply to Sparkybuoy's Post: when i turn on the car and the car is idle the tachometer stays consistent at about 1000 rpm's the car doesn't really shake until after a minute or two that it begins running with the a/c. If you were to be able to see my vehicle it is very noticeable that the entire engine shakes when idle.

When you turn the A/C on while it's already running, does the engine speed increase, especially according to the tachometer?

I would check the simple stuff.Have you had any tuneup work done lately?If not,you might want to checkout the tune up items.Distributor cap,ignition rotor,spark plugs and plug wires.Sounds like you are overdue for a tune up.
