common failures on 90
sure hoses cracked, all can be.
1: ISC on top of TB , loves to make noise, they go bad, and rattle bad. or jam open or closed. clean it is best, first.
2: IAC death. the wax pellet inside, goes bad after 20 years of endless thermal cycling... and can not be replaced like a thermostat
3: the thermostat can fail many ways (dead) stuck open ,stuck close or like my POS stat, took 50 miles to warm up (the slug stat)
4: missing thermostat. omg
5: some PO found a relic 160f stat and and stuffed it in,,, omg 2.
omg = oh my golly gee wiz.
finding a good use TB for 1990, near impossible
so some with bad IAC we add manual air valve to help cold starts. after plugging up the IAC port for ever.... if bad, near impossible to fix on any 90.
ebay is the only parts source under $1200 each (new from suzuki TB cost)
