I also noticed that when I start my car it starts out a litttle shakey before it idles smoothly. Could this be related to the coil or spark plugs? I'm very good about keeping up with oil changes and air fliter but at 70,000 I'm thinking I should bring my car in for a tune up. I usually don't have the money for tune ups but where should I take my car for a tune up?
Thanks

Dealerships are spendy, but independent shops can be risky, so I woud find one thats reputable, or you can just do it yourself, its not that hard, just change the oil, gear oil, fuel and air filter, pcv, cap, rotor, check your plug wires, that might be causing your miss, same with the cap and rotor, clean the throttle body, and run a bottle of top engine cleaner through a vacuum line that goes into the intake manifold, your car will run way better.
