One of the tailgate shocks keeps popping off the ball (located on the chasis) whenever the gate is opened. I believe the shock was replaced once and seems to work properly. Is it possible the wrong shock was installed? I can't see how the ball part itself can be worn down so much; it certainly doesn't appear so. Is it possible to maybe spot weld a lip onto the shock end or crimp it in some way to prevent the popping off? Also, I understand there's a third shock to hold the glass part open. I don't even see one. Bentley's talks about it some and mentions a special tool, but doesn't describe use of the tool. Is this a tricky thing better left to a garage?

Stumbling cured For quick back of the envelope calculations when you're not near a computer 1 bar ~ 1 atmosphere ~ 14.7 psi ~ 760 torr ~ 29.92" Hg.

Stumbling cured Hi All, I found a site that does conversions from PSI to BAR. and indeed found out that a fuel pressure regulator calibrated at 2.5 bar is running at 32 psi and a fuel pressure regulator calibrated at 3.0 bar is running at 43.5 psi. So that would definately confirm that the FPR that I installed in my car to replace the original old faulty one, was in fact the culprit for my stumbling problems. Car ran lean due to incorrect PSI/BAR rating, heated the exhaust up too high, created unneccesary heat within the vicinty of the feul lines near back seat of drivers side, caused fuel to boil/expand, causing cavitation in the fuel system, and therefore causing the engine to stumble. Now all I have to get done just for safety sake, is change my fuel filter, and have the resonator in my custom exhaust system moved away from the feul lines, or have a heat shield put in between them, to ensure that no extra heat gets to the system and causes me trouble. Lesson I learned, saving a few bucks on the FPR almost cost me the entire car, and almost lead me to replace a good fuel pump, in tank and out of tank, as well as a cold start valve to try and solve the problem..

Technically, not true - a lean condition can significantly elevate EGT. Whether this is germane to this problem is (of course) another story. - -John ------------------------------ Date: Wed, 19 Feb 2003 16:06:55 -0500 From: "Gary Derian" <[EMAIL PROTECTED]> Subject: Re: [uuc] <E28> Found the Culprit it seems.. Re Stalling Rough Idle Ongoing issue Peak temperatures are achieved at stochiometric fuel mixture. Going leaner or richer than that will reduce temperatures. Normal operation for a car with EGO feedback is stochiometric everywhere but full throttle.

As I recall, that person was told by the distributor that they had a part supercession note that stipulated they should ship the low pressure unit in place of the requested part. Anybody else recall better details of this thread?

I can't tell where the water is coming in -or where it's supposed to drain. Is there a bulletin or other tip on ensuring I don't have to replace the DME -again?

It seems like this is a popluar fluid, but not with the track crowd. My friend Bill and I are doing The Big Flush this weekend (both our cars), so he has already picked up some of the Valvoline fluid. I'll have to flush it again before O-Fest in October (assuming I can get away for it), at which time I'll probably go with the new and improved ATE SuperBlue.

Better find a better data source. 1.0 bar = 14.503 psi so 2.5 bar = 36.3 psi and 3.0 bar = 43.5 psi Of course you have no way to know whether I'm a better data source ;) Neil 96 M3 ------------------------------ Date: Wed, 19 Feb 2003 17:07:25 -0500 From: "Eurowerks" <[EMAIL PROTECTED]> Subject: Re: [uuc] bashing parts suppliers before giving them a chance- not nice! Before you publicly bash the PartsBin.com, WorldPac, and all of the other wholesalers/retailers that use WorldPac, did you call the supplier and see if they didn't send you the wrong part "accidentally"? Keep in mind that I receive parts from all over the country everyday, and I have to deal with incorrect parts or defective ones almost daily. I can understand your frustration. I can only say that in my experience, I have had more incorrect parts and defective parts from the dealer than from all of the other combined. You do realize that BMW does not make ANY of their own parts. They rely on the same parts suppliers that WorldPac does, they just repackage them and sell them for a little more money. Don't get me wrong, sometimes the dealer is the best place to get parts, because USUALLY they get you the correct part first, and I use the word USUALLY with caution here, as normally I get something totally different than what I actually ordered, even supplying them with the part number, and they give me something totally different, number and all. The bottom line is we all make mistakes, some more costly than others, but mistakes none-the-less. I think that if you had given the original supplier of the FPR a chance to correct the problem, they would have gone out of their way to correct the mishap. No, I do not do business with the people you mentioned, nor do I have any affiliation with them, but I do know them and know that they are reputable people that try hard to please customers every day. Sometimes it is hard to please everyone, especially someone that is shopping online, that usually goes to the cheapest price, and has no real loyalty to them, just loyal to being cheap, or frugal if you prefer! I am not accusing you of anything but jumping the gun with accusations! Please do not take my "cheap" comments to heart, I speak from experience from doing business online for years. (not any more!)
