Hi, I’ve recently purchased a 95 4Runner auto with a 3vze. It was a slightly wrecked rig. I replaced the front clip with a new radiator. It idles okay when cold starting it. When the temp came up and I was adding coolant as needed it began to run rough and eventually stalled out. It still starts and will run feathering the gas pedal when warm. It runs smooth all through the powerband it just will not keep an idle at operating temp. Any ideas?
