Car runs rough when the engine is cold

I think you get better value going with the first two options. Not sure if you can do this with Torque, but with my scan tool I can record data while driving and then go back and look at it all later, so that's a very powerful feature.

Hello Behlinla,

After some investigation, I think I prefer the ScanTool.net LLC - OBDLink SX Scan Tool/OBD Interface - ScanTool.net OBDLink SX $: $49.95

Based on the website, the OBDwiz diagnostic software is FREE.

Question> Is it true that the device (i.e. OBDLink SX) is the ONLY item I should buy for common diagnosis of OBD-II information?

Thank you

That is all you need. Just the device and the software. Assuming you have the laptop already.

HeHe That's a good assumption

I have 7 different kinds of laptops at home and no matter old/new, they are running good!

Thank you and Have a good night

So far my idle is fine if I understand it.

In cold weather, when I start the car, the RPM will jump to 1000RPM and stay there. This morning is around 45F and I found when I stopped at traffic light, it idles around 700RPM and stay there.

The engine oil over-refill has been corrected by the local shop which charges $115/per hour for labor. It surprises to me that they can do such a bad job with such a premium labor fee.

Will do oil/filter change myself in the future to save time and keep the quality
