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?

If the engine has sat and the ECU has been without power it will take 15-20 mins for the ECU to learn what the motor wants. If you can give it a drive, it will (should) improve.

Good info! As of yet, I don't even have the cooling system or alternator installed, just a battery on a bench charger. I'll move onto those items today so it can run for more than 30 seconds. Also been reading up on the ECU capacitors and I'm certain it needs those as well.
