Swapped a 1UZ from a 93 sc400 into my trooper. Only been a year so far lol. Cranked it for the first time today and she runs! Very low, but smooth, idle. Fiddled with the tps some but couldn't get it sounding right. Doesn't seem to do any sort of cold start high idle either, just bumbles to life and sounds like it's around 400rpm (no tach yet). What can I check?
