Hello there, thanks for using 2CarPros. Com. Are you noticing the miss at idle or driving? For a quick check you can try cleaning the throttle plates and do an inspection of any vacuum lines. Also, I see with the low mileage you have in the year of the car it must have been sitting for awhile. So check wires under the hood and look for any critters crawling around. Mice love to chew on wires. But some more information on the vehicle will help, any other symptoms.

Have the miss at thirty to forty mph. Is it possible it is a timing problem?

Hi and thanks for using 2CarPros.com.

I think I just sent you information on timing marks. LOL Regardless, it could be a timing issue or several other things. Things such as fuel pressure, engine vacuum leaks, needing a tune up. Can all cause a misfire.

Here are a few links that may be helpful for you. Take a look through them and see if they help.

This link shows a newer car with OBD2,. However, read down through it and you will locate info on spark plugs, engine compression, spark plug wires.

Let me know if this helps or if you have other questions.

Take care,
Joe

Where is the timing marks on the bottom pulley for timing. I cannot see one in the picture you sent or on the car. Do you have a clearer picture. Thanks.

Hi. It should be in line with the crankshaft pulley locating pin. It is not a very big mark.

Let me know.
