I'm still struggling with my '93 Bonneville running rough; on cold starts I get a check engine light. The local guys gouge for reading out the codes; one alternative I've had luck with in the past is to buy a scanner on eBay and use it until I'm done with the car. (I did this on my '80s GM cars with no net outlay).
I can't seem to figure out exactly what unit is required with this car, though. Any help appreciated. (Alternatively, anybody in the Raleigh/RTP area with the ability to do this can let me know!).
