okay guys i have a problem with this damn car i just rebuilt the motor after the timing belt put a valve through the piston, whole new bottom end pistons crank everything and a remanufactured head. got everything back together and it would not idle so I replaced the tps brand new and got a new ecu just in case now it idles high but not all the time. When i first start it it's just fine idles at about 900 to 1000 which i stil think is high, but as soon as it warms up it idles at about 1800 to 2000 and i can figure it out any ideas? Its a 2004 4 cylinder automatic.Also there are no engine codes being thrown so what do i do?

What about the idle speed control actuator (ISCA)? Its mounted by the TPS. I believe they have the same connector so I'm wondering if the connections are swapped (if thats possible). The ISCA and TPS both have 3 pins and have a blue and pink? wire for pins 1 and 2, respectively, but the TPS has black wire while the ISCA has a yellow/orange stripe wire for pin 3. You may have to remove the shroud around the wires to identify. I hope this helps.
