My 2001 SL1 1.9l idles high. Just changed oil, filter, plugs & cleaned intake (which was full of carbon). Now it idles between 2 & 3 thousand rpm. Engine also runs very cold as if the thermostat is stuck open. Any pointers as where to look for the problem? Thanks.

Idles high-could be vacuum leak/sticking throttle plate or kinked throttle cable-or a problem with the idle air control valve and throttle position sensor.

Cold engine -replace the thermostat
