Not only KR related, but here goes: I have been in need of a tow vehicle for my Kr trailer, my sailboat trailer, cabin cruiser trailer, UH-16 hover craft trailer, The 1958 skagit skimaster trailer, and the box trailer (residential dumpster)..
Yes, that IS a pattern.. So, this weekend (off of craigslist) I bought a 1989 4 wheel drive chev suburban powered by a 350. It ran great when I test drove it. I bought it and within 45 minutes on the road it started running rough at idle and dieing at the intersections. I replaced the PCV valve, which made a difference but not the full cure. I tested the coolant temp probes, no faults there. The MAP sensor is suspect because it could cause the rich mix trouble, ( and the codes had a few map sensor faults recorded) but measured ok. (replaced that and it got better). Still not right. It idles perfectly once in a while but then gets rough and dies sometimes at idle. ANY Chev gurus want to chime in on this? KR relation: I need this to haul my KR to the airport! jg
