Has anyone ever had this problem?

I went to check my error codes, because the check engine light was on, and no codes registered. Nothing
came up at all. I even went to Rotary Power & they couldn't get any readings either.

Jeff at RP told me that he would have to swap out my computer for one of his & then read the codes. He is so booked up that he wont have any openings until 2 weeks from now.

I'm just asking anyone out there if they've had the same problems & what was the remedy?

Thanks
