Hi I've been having problems with my car. It seems to shake when I accelerate it, like it wants to turn of.
what do you think the problem could be?

This sounds like a vacuum leak. However, we need to start with checking for codes.

Here is a guide that will help with getting OBD I codes:

Below you will find a chart on spark plug issues. We need to check this and pull the plugs and see if they are fouled. This could be a misfire or just worn spark plugs.

Please let us know what questions you have and what you find. Thanks
