Default the battery has been completely drained a couple times

but the Voltage is reading fine and there isn't any hesitation starting, so I'm leaning away from that.

I didn't know the CTS played such a big role...I'll give that a try. I'm on my second one now. When my first one went out, it was just giving me wrong readings on my Coolant gauge; nothing nearly as dramatic as this.

Default Just go into regular measuring blocks, hit GO on Channel 0, and enter the others

Logs are written into the VCDS\Logs directory as .CSV files.

Default Engine CTS - There are several temperature sensors on the car

This is the one used by the computer.

The instrument cluster one is either on the radiator or on the coolant expansion tank---those are different ones.

Default Sounds like a vacuum leak around the TB area, check the TB gasket

spray disc brake cleaner around the base and be careful not to get it on the electronic controller otherwise you can damage it. If the idle increases or stabilize, either the gasket needs replacing or the bolts are loose.

Replace your spark plugs and add a can of BG-44K fuel injection cleaner to gas at next fillup.

Default Re: this one? - Check throttle body...

Definitely check the throttle body. With time you get a lot of carbon build up. You should probably have it cleaned and then do an adaptation.

Default yes. not sure if you need the blue or the green one since you're '99.5

but my '01 uses green.<ul><li><a href="http://www.purems.com/products/product.php/II=1472">http://www.purems.com/products/product.php/II=1472</a</li></ul>

Default

thanks for the link. IIRC, mine is blue but I'll double check before ordering.
