Wow, that was a whole lot easier than I thought it would be...I pulled the OVPR out, and none of the solder joints really looked suspect, but I went ahead and re soldered them all anyway. I reinstalled it, and used some electrical contact cleaner/enhancer on the connector. It looks like the repair was a success!! Car started up perfectly, no ABS light, and it has never idled so smooth.
It's still not perfect (needs a full tuneup) but it is one HELL of an improvement, that's for sure. I can't thank you guys enough!!
