low compression, leaky injectors, bad sensors....could be any of the three...

I'd check the compression first just to get that out of the way...if that's good, then i'd check the resistance on the thermoswitch on the back of the t-stat housing. if it's bad, replace it. It's the sensor with the green connector below the alternator. I'd probably check the O2 sensor too...

It's the thermoSENSOR, not the thermoswitch. The thermoSWITCH is a grey one pin sensor next to the thermoSENSOR. But I say check the o2 sensor first, how long has it been since you checked it?
