Compression's are okay, look for a bad plug or lead. check for tracking around the coil this is a pencil like carbon smear or line which would indicate a voltage leak to ground. faulty injector or a vacuum leak. also, a code read will be of help, start here.

Hi GLEN DIXON.

If you decide you would like to conduct the scan yourself here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us so that we can further assist you. We are always happy to help.

Thank you for visiting 2CarPros.com.

Kindest regards,

Renee
