Yea, you'll be better off buying a new belt. But giving the the situation (getting married) that I'm in, I'm going to be broke..

That's the correct line.

Acura Legends? OMG, junk! They are notorious for blown headgaskets. Every single other Jap car, I can vouch for reliability, but Legends are trippen balls. Haha. 120k and I'll see one, for a headgasket. As a member, I'm just trying to give y'all a heads-up. I'd stay away from Acura Legends...I can probably change the headgasket, drunk.

Would a "bypass" system effect actual oil pressure? I'm running a turbo and cannot afford to have an oil pressure drop within my system. Yes, it'd be an environmentally friendly approach to the situation, not to mention, reduce oil change intervals/money spent. But, I have a 15k motor on the line. I'm more than happy to reduce oil change intervals, via an external bypass but, please explain.

Here you go, http://us.lexusownersclub.com/forums/index...;st=15.....look at post #29.

Yes, I agree with jzz30 and Rx330driver...just keep it safe and stick to the tracks. I have a daily driven monster but street racing is for losers...I'd rather flex my power safely, on the tracks.

If he is an experienced shifter, you'd lose...hands down. You wouldn't be able to "hang" with his 1st and 2nd gears.

Sounds like an aged belt. Try replacing the belt or buy a bottle of "belt dressing". Or just double check and make sure that there isn't a cricket under the hood.;)

Have you checked the spark plugs? It seems that the codes are pointing to a problem within cylinder #1. Maybe the spark plug gap on the first cylinder is off. But honestly, don't solely rely on a code to help you solve the problem. The codes you're "pulling" is only an aid to the diagnostic process.

Check your transmission mounts.

Carb cleaner or propane would work to find intake vacuum leaks. Did you replace the manifold gasket? Spray some carb cleaner around the suspected parts and if the RPM suddenly increases then you have found the vacuum leak. Carb cleaner is extremely flammable, so I'd use it with caution.

There isn't really a fix for it, besides replacing the converter itself. Just do the regular fluid changes on a timely matter and drive it until it gives.

Walmart

What happens after the 10-12 years? All uncommon parts are special ordered or unavailable?

The 1st gen SC is a legend; BMW is a German piece of junk. It always will be. I don't care if they put a 10 liter V20 in that BMW, you're Lexus is still better.

I guess my car is a piece of junk. Maybe I should trade it for an old school SC.

Cmon now, everyone should own a BMW at one point in their life. The driving experience is a living legend itself. ;)

Normal for a slipping torque converter but not for one in good condition.

A bad ignition coil is likely. You might want to check caps and rotors also. The car definitely is running way too rich, though.

Conventional O2 sensor's: above 450mv = rich, below 450mv = lean.

With a typical O2 sensor the ECM cannot tell how rich or lean a mixture actually is. All the ECM attempts to do is maintain an average sensor voltage of 450mv, to maintain a stoich a/f ratio. The lower the exhaust flow the less activity you'll see from these sensor's. They are simply not as acurate as A/F sensors.

A/F sensor's output is linear, increasing or decreasing with mixture strength in the exhaust system. These sensor's have a diffuser chamber that measure oxygen ion flow between chambers, that info is then sent to the ECM and processed as "actual oxygen content".

Operation temps and warm-up time also differ between these two sensor's.

Sensor output:

O2 Sensor - 0 to 1000mv

A/F Sensor - 0 to 5v

The timing belt would be at the top of my list, followed by everything else mentioned above.

Check to see if the dealers have any 2006 LS 430's left, you can probably get one for nearly the 2006 used price you quoted. We paid only slightly more than that for our new one in Feb 2006, which had the Modern Luxury package, 18" wheels, mats & nets, plus all the normal stuff Lexus adds on.

Actually I already got a 2004 LS430 Ultra with 46K miles for $35K. Amazing deal. Car arrives in a few days.

I must admit I am prety disappointed with these forums - I had 3 pages of responses on ClubLexus within 48 hours of my original post. It took nearly a week to get a single post here :(

Cmon now, watch the foul language. :P

I'm actually tempted to part out my car. I might actually be able to buy that Ferrari that I've been dreaming of owning.
