I start the engine for warm up after a cold winter night. Then it started to shake real bad. What could be the problem?

Hi,

This could be the result of several different things. For example, it could be a fouled spark plug or low fuel pressure.

If the check engine light is staying on, you really should scan the computer for diagnostic trouble codes.

Here is a video you may find helpful. It shows how to scan the vehicle.

What I would suggest is this. If the check engine light is on, have it scanned. If you don't have a scanner, most parts stores will do it for you free of charge.

If there is no check engine light and the vehicle hasn't been tuned up for a long time, you may want to consider a general tune-up.

Here is a link that explains how to tune up your vehicle:

If you look at the pics below, they are the directions specific to your vehicle for replacing the spark plugs.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
