Can you communicate with other modules?

Have you tried another scan tool?

Is there power and ground at the data link connector?

Can you go into more detail on hunting?

Since it runs the communication concern is not the ECM.

Rich issues can be to blame on a restricted air filter, dirty air fuel sensor, vacuum leaks, and bad O2 sensors.

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.

Thanks Chris
