---------------------------------------------------------------------- Date: Thu, 27 Oct 2005 20:15:16 -0500 From: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> To: <[email protected]> Subject: Re: E30 accelerates in stages Message-ID: <[EMAIL PROTECTED]> For some reason, both the M20 325e E30 cars AND the Non vanos M50 2.5l (E36 325/E34 525) have a nasty accelerating-surging problem that shows up at higher mileages. The two engines are so wildly different I would be surprised if the problem is the same on both. I know of several cars with these issues and have not chased the problem down, but an quite interested in ideas for fixing it.

I am anxious to check the AFM. I also have an idle problem where after I come to a stop, the idle will be at 800 or 900 and will slowly drop down to 600. Sometimes it will just fall quickly.

BMW worked so hard at making these new fangled e36's so COMPLETELY different from the O2's that they even put these funky sensors that detect any "O2-ness" that may creep in, over the years, as we try to keep these plastic cars alive as long as we did the with the 2002's. (JOKE!) Seriously, it was the Oxygen sensor. O2 sensors are wear items. My '86 325es did the same damn thing and I cured it the same way. My mechanic/friend had to remind me and then prove it to me with his MODIC, that although there was no Check Engine light illuminated, the sensor was out of spec. I'd bet if this car was OBDII that CE light would have burned through the dash by now! (another joke...) Good luck bro, I hope that helped. Paul A.

I am WAY over due on my replacement of the O2. That was one of the things I wanted to check this weekened, but the process is sooo involved (atleast in the Bentley). I will look into it.

Target stores in Los Angeles reduced the price on Mobil 1 to $1.2x. It is only on 15W-50W. It is not marked as clearance as there is no sign nor do they sit in the end caps. Maybe no one buys these anymore so they are getting rid of them. If you drive by a Target on you daily commute, it might be worth while to stop in. However, most stores might be out of these already. One of the Target stores also had Castrol Syntec Blend for $.62/qt, but only on 10W-30W. Again, YMMV. __________________________________ Yahoo!
