Dizzy Very Wierd Heating issue SW2 1995 DOHC

Ok so my problem I believe to be one of a kind. My problem happens when its cold or even on a good day at 60-70ish my sw2 will not really warm up like its supposed to and eats through my gas faster at cooler temps. know what's confusing me is how fast I can loose what little heat I've gained while sitting at a light at idle. any thing over 35mph for less then a minute an my sw2 is arcing up the rpms again to try keeping hot, And forget about turning on the heater in the car. I know its supposed to be able to at least maintain the 1/2 heat but its never gotten above 1/3 mark. Could it be a stuck thermostat or something with the radiator. I know my friends car has a set screw in his for winter to help heat build.

Also this is some what unrelated I think, But any time the car ever did get above 1/3 mark It seems like am loosing power bogs down. I will also add I burn oil on cylinder 3. the other three are just fine. My head is perfectly fine as wheel had that checked. I really need heat not just for myself but for the burn hole in my wallet from so much gas be yous'ed


I've been really lenient on posting here since last time no one seem to know what a evo sensor was >.> but that's nether he nor there

REWARD EXCELLENCE!

You need at least a new thermostat of the OEM design. That means a STANT 14279 and the original OEM thermostat housing. Then if it has never been done the ECTS, that is the 2 wire sensor, replaced with a Standard Motor Products TX73 or equivalent. Search will bring up the how to change it without twisting it off instructions. Also inspect the inside of the connector for any foreign material and inspect the 2 wires back to the main loom for any splices or crimp connectors. If you find any of those cut them out and properly solder the wires.

REWARD EXCELLENCE!

No, that is the EVO Solenoid. There is no discreet EVO Sensor ...

Thank you for the answers. I forgot to mention I've replaced both of the coolant sensors. They where buy the head or at least one was in it. But the thermostat I didn't think of housing it goes in. Also is the any way to test my gauge for Accuracy. with out polling the dash.
