Question:

Malfunction Indicator Light is on, idles roughly, when accelrating car shakes. Whats wrong?

I have noticed for a little while that while I am idle my car steering feel vibrates a little. The other day I was driving and noticed that whenever I accelrate or put my foot on the gas even a little it drove like the tires needed to be balanced very balaced (shaky rough etc). Now my malfunction indicator lamp is on which says there could be an problem with my emissions system. What does this problem sound like to you? It is a 3 yr old car with about 40,000 miles on it. Is this a serious problem? How much do you think it will cost for parts and labor. I have not had a new car before this one so I never had to decide whether or not to bring it to the dealership to get repaired or an auto mechanic in my area suggested by a friend. WIll the dealership rip me off?

Answer:

The only way to tell for sure is to have the codes retrieved from the computer. Sounds like a misfiring problem to me. No way I can estimate the cost. If the car is out of warranty, take it to an independant garage as they will be cheaper than the dealer. Get recommendations from friends before choosing the garage.rkb
Could be simply a loose spark plug wire.?
It could be just about anything. Most auto parts stores can pull the codes and tell you what needs to be done.
