Message-ID: <[EMAIL PROTECTED]> That would admittedly be a pretty tight fit. But since it was a 24-foot trailer and a considerably shorter car it wasn't such a big deal. But you probably suspected that. Unfortunately it's as easy to mis-shift the "/' key as a BMW.....

Thread comments follow. 4 resistors still less than 20% of Bosch cost for stock unit. Tom: Yes, 4 25 watt 0.62 ohm resistors wired in a series-parallel circuit will give you a 100 watt 0.62 ohm resistor. 7.5 amps at 14 volts is 105 watts, but the starting current of the fan will be higher than the operating current. The 100 watt package should be sufficient.

Message-ID: <[EMAIL PROTECTED]> Recently picked up a 318is to drive as a beater, mechanically everything checked out, but the first time I drove it to work (50 mile commute in rush hour L.A. traffic) I noticed something very odd: When the car sits in traffic for a while, idle becomes erratic and the throttle does not respond. First symptom would be that the idle will fluctuate a little, between 700 RPM to 400 RPM, then when I press down on the accelerator NOTHING happens for a little while, between 3-5 second lag and then the engine slowly climbs out of idle. While the car is moving everything is fine. It's only when the car has warmed up and sits in traffic, or when I've stopped the engine only for a short while, like if I stopped at a drive-through. Car has ~170,000 miles on it, picked it up only a few weeks ago. Since the problem is hard to replicate, except only when I'm sitting in heavy traffic after the engine has been running for a while, it's hard for my mechanic to pin-point the problem. Anyone else have any bright ideas? -Dan Wu ------------------------------ Date: 24 Jul 2005 17:57:02 -0700 From: [EMAIL PROTECTED] To: bmwuucdigest@uucdigest.com Cc: [EMAIL PROTECTED] Subject: Re: Auxilliary Fan low speed resistor option Message-ID: <[EMAIL PROTECTED]> Cheap solution. Depending on the current, that resistor can get hot enough to melt plastic cable ties. Keep an eye on it.

Message-ID: <[EMAIL PROTECTED]> Perhaps for easy highway driving running regular may save money in the short term. With any significant load, I think you will save nothing, and risk some long term damage. Premium is a better deal now than it was 5 years ago. At 1.25/gal, premium was 20 cents more so 16%. At 2.50, premium is still 20 cents more or only 8% higher. Gary Derian > > Dumb question of the day.
