Slow to accelerate. Engine jumping (worse when the air conditioner is on). Check engine light been on for what seems like forever, but now occasionally it blinks.

Hi KT Edwards,

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. 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.
