No need to pull the dash for TXV replacement. The cooling unit can be removed with the dash in place: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=AC&P=33 http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=AC&P=34

I'm afraid you are limited by law. Really doesn't matter which brand you choose since all pre-OBD II converters installed under the new law effective 1 January 2009 must be tested to meet the same increased performance standards, have the same labeling, and carry the same 5 year/50K mile...

And it's not his fault you're 51 going on 22. I can see it coming from kids and 20-somethings (same difference) but becoming overly attached to inanimate objects is a something you should have grown out of long ago...

Kckazdude: Good for you. While the alarm relay isn't always at fault if others bothered to employ that simple measurement technique they'd find it's almost never the actual wiring. At least it's never been on the cars I've repaired after removing this hack and it has never been at fault on my...

In theory it's not that complicated. What you're shooting for is a stoich exhaust stream going into a healthy catalyst. That along with a working EGR system will make the engine pass. If worst comes to worst put a new cat on. The increased efficiency will very likely knock the HC down low...

You can try but it's tough to accurately duplicate the ASM. I used to jack the rear and load it with the e-brake but now that I've got a portable I just drive around and let the anaylzer log everything. Fwiw the ASM was developed mainly for NOx testing but HC does increase with load even on a...

Not the best way because anything introduced through the booster line will have poor distribution across cylinders. I have a port welded onto my EGR manifold fitting but you should stick with injecting it somewhere upstream of the plenum. Frankly I wouldn't expect this to solve your problem. An...

Since Bosch invented the things I'm pretty sure they know how to make one. Couldn't hurt but your CO already shows the engine to be in fuel control. If you really want to know measure the sensor and see. Water won't clean intake deposits. For that stop buying crap gas or start using an in-tank...

Actually deposits will cause high HC, especially valve deposits, by absorbing fuel, but I'd focus on the ignition system. It's usually (but not always) the culprit behind HC. And O2 sensors do go bad but your's looks to be good. If it wasn't you'd be running rich...

If you bought an O2 sensor you just did...

^ Indeed. And he needs to get closer with that ear...one inch is too far :)

You're kidding right?

^ Induction leaks do not raise idle speed on L Type EFI systems. They only effect idle quality.

Eh, stuff happens. At least you're more on track than your Cajun brother ;)

According to his profile he's GTE. That means one sensor even in Cali. Regardless, throwing parts at the car is dumb...

Speaking of Edmunds, it's a longish read but enlightening: http://www.edmunds.com/advice/buying/articles/42962/article.html

No "drawing" or "pulling" goes on either ;)
