Alexander the o.k is back

On the end of the egr rail, going toward the firewall. It appears to attach to the valve cover which has a nipple which is covered. Took the cover off and attached it and RPMS went to 250 from 750, ran rough. Runs perfect without it connected, (for years) so I plugged the end of it. The plug in the end is pointing to the supposed connection point. Any ideas what it is? Or does?

Good luck with it. Since there are no traceable codes to to pursue, the problems are multiple, unrelated, and intermittent- all this points to a short in the system. Or a faulty ground. Just my 2 cents. It looks like you've spent close to a $1000 trying various things w/ no result, so why not try it. Best part is it will cost nothing, can be done in 30-40 minutes, and if they're good, you can rule that out and look at yours grounds. I think there are at least two or three, not sure where tho. I've owned my trusty ls400 for about 19 years and can safely say it is the absolute best car I've ever owned. Hands down. I may do a post showing what items I have NOT had to even replace in all those years, including the original fuel filter and pump! Still have the originals on there. Front struts- never been replaced. (well they may have been after the deer fiasco but that was 17 years ago!) And on and on. Just amazing. Love this car. Please let us know what you find since that helps us all. With the LOC as a resource you WILL be successful. Best of luck.

Looks like they got it right on the side/ rear views, but screwed the pooch on the over the top grill work. I know the designers have to come up with something distinctive, but just... wow, not good. Reminds me of a baleen whale. But then I'm not much of a grill guy, except to put steaks on... Inside is stunning tho.

These seemingly unrelated problems sound like the old chronic Ls400 trunk hinge issue: http://us.lexusownersclub.com/forums/index...showtopic=50087 "This same type of problem happened to me about a year ago. This smooth world class car started balking, cutting out, lurching, wild rpms, dash flickering, radio went out when hitting the brakes, just seemed ready for the junk yard. It happened all of a sudden. No warning. Now it's smooth as silk w/ 255,000 miles on it. Open the trunk. On the left side you will see a wire harness on the left hinge. After repeated openings and closings the wires inside that harness become fatigued and frayed. Then they start shorting out. Then sputtering, and stalling. This is a design flaw and lexus knows it. If this describes your problem, then remove the plastic bracket on the left hinge, strip down the harness, untwist all the wires, re-connect, then re-tape.. Don't assume they are good- strip them down and examine them. Make sure to leave off the hinge bracket that ensures tension on the harness. Just let the whole mess swing free and loose. In my case, problem solved, and no spending thousands of dollars in diagnostics, parts, and tech snafus. Best of all, it's free. Takes about 30 minutes." Post back what you see at the hinge. Alex

Xiang, Sounds like incomplete combustion byproducts. Check all ignition related components such as: wires plugs distributors and most probably a failing coil. Search the forum your answer is already here. Other things to look for: oil / PS fluid dripping onto heat shield or cat. If you or a friend has an obd2 scanner, hook it up and post what you get. I think obd1 was thru 1993.

So, in keeping with the fun topic here's a lil tidbit: Coast Guard Drags Decoy Boca Raton Into Middle Of Ocean In Attempt To Lure Away Hurricane Irma "MIAMI, FL—Saying the plan was the best option for mitigating the potential damage from the storm, the Coast Guard reportedly towed a decoy of Boca Raton into the middle of the Atlantic Ocean on Tuesday in an attempt to lure Hurricane Irma away from land. “After evaluating all available options, we’ve determined that the most effective course of action is to tempt the hurricane away from real coastal areas with a convincing replica of the city of Boca Raton approximately 100 miles offshore,” said Coast Guard Rear Admiral Peter J. Brown, adding that the full-scale reproduction includes poorly constructed buildings for the storm to knock down, fake bridges it can sweep away in floodwaters, and power lines it can topple to plunge the manufactured city into darkness. “The fake Boca also has 96,000 mannequin residents Irma can torment as much as it likes, including several who appear to be antagonizing the storm with profane messages on plywood-covered windows.” At press time, local officials celebrated as Hurricane Irma had changed course, devastated the fake Boca Raton, and proceeded north to the Carolinas." <a>http://www.theonion.com/article/coast-guard-drags-decoy-boca-raton-middle-ocean-at-56846</a>
