Group, Got my DASC installed today and am very happy with the experience so far as well as the shop that installed it. That being said, I have an intermittent problem by which the car will be idling normally and then suddenly stall. It doesn't happen all of the time, but it will momentarily sputter and then stall. And it is random at idle OR when I'm coming to a stop. Any suggestions? Chris P.S. This is on my 97 5 speed. __________________ 2011 BMW X5d with EVERYTHING on it 2007 Cooper S (6 speed manual) 2001 Eurovan 1997 318ti | | | 10-26-2006, 01:37 PM | #2 | doesn't care about you.

If not, take it back to the shop and tell them to fix the damn thing! I assume you are getting a CEL too, what codes are you throwing? __________________ '99 Dinan M3 | | | 10-26-2006, 02:39 PM | #3 | TRETEN IRGENDEINES ESELS Join Date: Aug 2004 Location: Rhode Island Posts: 3,687 | Quote: Originally Posted by DustenT Did it do this before you installed the DASC?

The car did not have a smooth iddle and sometimes it'll stall. We fixed the problem by cleaning the iddle valve. 2. At certain RPMs, the car will choke. The crank sensor was not positioned in the correct spot. This may help. __________________ 1989 E30 325is 5s Coupe Zinnoberrot 1991 E30 325i Auto Coupe Schwartz 1991 E30 325is 5s Coupe Hellrot 1995 318ti E36 Alpine White III DASC (RIP) 1996 328i 4Dr Artic Silver (RIP) 1999 M3 Estoril Blue Metallic RMS Vortech SC 2001 325i E46 Alpine White - Sports Package (SOLD) 2005 E46 M3 Coupe SMG | | | 10-26-2006, 04:28 PM | #5 | Senior Member Join Date: Apr 2005 Location: Calabasas Posts: 187 | Sticky throttle post-DASC install Quote: Originally Posted by DustenT Did it do this before you installed the DASC?

The shop actually did a really good install. It happened while I was at the shop and the suggestion that was made was the the Motornic unit needed some time for 'adaption' in fuel/mixture values. This isn't my only post-DASC woe... I'm experiencing another problem that was there (albeit very slightly) before the DASC install. At that time, the throttle was a little sticky right as you touched it (gentle accelerator application). Now it is still there and it is more pronounced under harder accelerator applications. I'm begginning to talk myself into a throttle cable issue, but I want to see if others have had sticky throttles and what they have done?

This may help. | Before I had the DASC done, I had some slight idle surging. I assumed this to be the ICV and that it needed (spray-cleaning) to be done. At that time, before the DASC install, I wasn't experiencing any stalls though. I asked the shop to clean the ICV...But even if they didn't, I wasn't stalling before the DASC install. And remember: It is only intermitten stalling now.

Quote: Originally Posted by FATHER i think you have a vacuum leak...check the hoses | No leaks. I checked everything. I expended a lot of brake cleaner in the process. The system is tight. The only thing I keep coming back to is the idle control valve...What kind of load does the DASC put on the ICV? Mine is 138,000 miles old. Cleaned out, or not, is it up to the task at its age? My stalling problems are occuring as I come to a stop (while the car is warm). The engine will drop to about 200rpm...Struggle to raise itself back up and then stall. There is no 'hunting/surging'. It goes to 200rpm, briefly tries to pull out and then stalls. Anyone?

It has a MAF. That being said, I'm certain it isn't the MAF. Why am I certain? Because it is too coincidental. There were no idle problems before the DASC install...And now there are? Can someone comment on an idle adjustment screw?

PCV valve, are ok?. fuel presure? Oxigen sensors? remember that the cilicone glue Fu!@# the oxigen sensor super fast...the by pass valve on the blower are ok? in my setup mine have adjustment screw...spark plug wires are ok? sparks gap also... __________________ BMW...MY NEW TOY Mods: Some plastic parts, ///M Wheels and me | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
