kommies?, nah we are the good people. we are the most populous state in the u.s. wide variety of geographical features, very diverse culture and we get stuff done. did i mention some of the best food and wines around.

closed loop refers to the operating mode of the powertrain computer. try watching this: http://www.youtube.com/watch?v=oG_Xc1nP9aI

you can get a scanner to look at data for issues with tech support here. may want to invest in a scangauge2. can read codes and live data on its display as well as trip function like mileage and tank calculations. mount it where ever the cord will reach and enjoy.

thanks for video. iwas wondering my temp even when driving in 100 deg heat never goes over the line between 100 and 210 so 155 im guessing. where should it sit. always seemed a lil low to me but since it was not overheating felt it was fine. maybe check thermostat to see if stuck open.

use video as example tuck had been running for several hours. i have no cooling glitches just a pcm issue which is causing the power loss and shifting issue you see in the video. btw i use flex a lit 280electric fan kit so don't worry about the temp gauge sweeping a bit.

mine doesn't even get that warm when it was 110 with ac on. never goes over the 2nd fat line

if a scanner reading about the same from it connection to a different coolant sensor then thermostat is very likely stuck open. or if you don't mind a quick mess now drop the coolant level some replace it. and be prepared to top off radiator but then later the reservoir a few time when cold. eventually it will level out. you need a 195° thermostat. don't let anyone sell you a different one. and yes it will work well in kingman weather. i was there a few months ago.

got the live data read and coolant temp was at 188. so my temp gauge is a lil off. so im guessing it has a 195 thermostat. I couldn't see with the scanner if it was closed or open loop but thermostat is working correctly.

while it is running look for temperature swings in the data. like start cold, watch what temp it goes up to and what it drops down and back up to again. post results here to see if it is actually working. unless you saw it do that don't presume it is working yet. what other kind of data can you read?

It was a friends scanner. I was mainly looking to see if the temp was up where it should be. When we first plugged it in after I drove over there it was at 198 while sitting once I started it back up went down to 188. I'll see if I can borrow his for a hr or 2. So just watch the coolant temp? I'm pretty sure it shows timing o2 sensors and more just really dont know what to look for

yep.
