99 SC2 Rough idle cold
New member here. I have had my SC2 for about 2 years. No problems until now. It is starting to get cold in the mornings here and after starting she will idle rough, but not every time. If I rev it a couple of times it evens out. Sometime almost stalls. I have gotten a check engine light a couple of times while it is warm. The code is for the EGR solenoid valve. The light will be out the next time I start it or will extinguish while I am driving. I have read a lot about the ECTS. Could this be my problem? Any help would be much appreciated.

As touchy/spooky as the original ECTS units were, I'd opt for a replacement as soon as you can afford it. Change the electrical connection pigtail at the same time, to make sure you get a really good connection

Check the connector first on the ECTS. I found out that mine was cracked and not making a proper connection. I may have replaced the sensor for no reason. The damned connector cost me $27.23 at the dealership and the sensor was only $19.24. BUT the sensor was made in China. WTF? Inside the little bag it came in was a slip of paper that clearly says MADE IN CHINA. I'm keeping the one I took out as it was a brass tipped one too. I hope to never need it, but at least I'll have a back up to try if I need to. Part # on the sensor is 21025106 and the pigtail is 12117087. Just in case you want to order one or the other.
