Looking for someone who can scan my 330 to see what's causing the check engine light to be on. Car is "shaky" vibrates when you start it and drive. Light goes off after turning car off but as soon as you start it up and drive off... the light comes back and the car continues to shake. Anyone nearby who can help me scan it?

Thanks

Go to autozone, they'll do it there, I think its free.

Sounds like a misfire, it should throw a OBDII code for that.

I'd be willing to bet you've got a dead ignition coil.

Try autozone as others have mentioned. I always take my car to Eurowise which is off Woodlawn (Springbrook St) Mike does great work for less and now has aa Autologic system he uses for diagnostics.

+1 and easy to test for too as quoted from another forum member. "have your car running and pull each coil out 1 by 1..Basically take the first one out and if it sounds like its gonna stall or losses power or sounds funny then you know the coil is working, put it back in and move onto the next coil.. When you pull the coil and no change is made , then that is the faulty coil.. Depending on how bad and how long you been riding your car like this, your plugs might be fouled from all the unburnt fuel"
