I tell you, buy them books, send them to school..... I'll go and check it. At least I have somebody I can blame it on. ;-) Pingger -----Original Message----- From: Jim Bassett [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 16, 2005 11:29 AM To: [email protected] Cc: Gordo, Ping Subject: Re: [UUC] CE Light still on!!!!

It likely says on it somewhere if it's 8 ohms or whatever. A resistance check will tell you whether the voice coil is shorted or open. You should also get a TIC when you connect your ohm meter to the leads - another confirmation that the tweeter is capable of tweeting. You should see a variable AC voltage across the speaker leads if you want to use your meter to check that. ----- Original Message ----- From: Jonathan Brush [EMAIL PROTECTED] To: [email protected] Sent: 8/16/05 3:01 PM Subject: [UUC] <E34> Tweeter inoperative > Gruppe: > My '92 535 factory stereo puts out no sound to the > driver's door tweeter.

Thoughts and opinions appreciated. I think I remember people mentioning that if the transmission is a ZF then you should use Red Line D4ATF, other folks have had nice results with Mobil synthetic ATF. I think the type of drain plug is another general rule of thumb, innie = MTL, outie = ATF. I think Red Line on their site specifies the color of tag on the side of the trans to judge which fluid to use, how boring. ;-) If you have a Getrag then I believe the Red Line MTL you ordered is probably fine. On my E30 (Getrag) I run Red Line MT-90 to try and quiet down a noisy input bearing (?) and the ltw flywheel. On my E30 M3 (again Getrag) I ran a mix of MT-90 and MTL and it quieted down the input bearing noise quite nicely. On my '98 M3 I just put in Red Line D4ATF the other day, no noticeable change, the damn thing still grinds downshifting into 3rd when the tranny is cold. Damn E36s! :-D Carlos 98 M3 E30 325is x91 M3 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

A customer had his transmission popping out of 1st gear, after the fluid change to MTL, no more problem... Redline MTL all the way.

What is the > juice to put back in this thing? For a street-driven car, I would follow BMW's rec and in this case re-fill with ATF. I use Red Line D4ATF in the '98 M3 5-speed; I believe Red Line makes a "regular" ATF as well. Having said that, I use Red Line MTL in the race car for it's slightly thicker properties. Makes cold shifting rather stiff & notchy, but hopefully shouldn't turn to water in race conditions <g>.

Message-ID: <[EMAIL PROTECTED]> I see it written here and there that you should keep your air filter clean because a dirty air filter decreases mpg. I can't figure out exactly why this would be true. If your filter is dirty, you have 2 restrictions in the intake - the filter and the throttle body. With a filter restriction, you operate the throttle a little further open and the engine operates as usual with the exact same manifold pressure. The situation changes if the filter is so clogged that you operate at WOT often to compensate of course. But what's so terrible about a dirty filter other than the top end power loss? ...hoping to spur some interesting comments... -- "It is an honor to be Cookie Monster." -Sesame Street spokeswoman Audrey Shapiro ------------------------------ Date: Wed, 17 Aug 2005 13:28:30 -0500 From: Clarence <[EMAIL PROTECTED]> To: John Bolhuis <[EMAIL PROTECTED]> Cc: [email protected] Subject: Re: <misc> dirty air filter affects mpg?

Message-ID: <[EMAIL PROTECTED]> That piece of conventional wisdom is rooted in the old carburetor days when a clogged air filter would cause an enriched fuel mixture. With fuel injection and oxygen sensors, it makes no difference to cruise economy.

Message-ID: <[EMAIL PROTECTED]> Another point of view may be to point out that the engine speed is not controlled by restricting air flow, but by modulating fuel. At any given point in the curve, it is best for the airflow to be completely unrestricted to give the combustion process the maximum efficiency.
