I bought another 93 ls for $300, I knew it had some problems but I'm stumped on this one. Like I said its a 93, it has 168k and it very good physical condition it just runs like crap. It ended up having some firing issues which the previous owner never looked into. Ended up being simple. Bad cap n rotors shooty plugs and wires. I had it running like a top for awhile. Now I have a few new problems. When it gets to normal temp I get very rough and low idle(under 800 rpms) and it stalls out. Im going threw a list of what it might be but nothing has fixed it yet. The power steering is leaking bad now and I get the white smoke from it, alternator is most likely shot too if that helps. I have a new pump and alt to go in soon as I figure the idle out. The oil is clean no antifreeze and the oil level doesn't drop.

At a cold start the engine runs flawless, perfect idle no stalling. So I'm figuring it must be something temp related. If anyone has any insight to what may becausing this it would be extremely helpful

the first two things i would try are new Engine Coolant Temperature Sensor (here is the cheapest source for OEM) and next a real Toyota thermostat
