Here's why I ask. I was experiencing erratic idle at startup, then it would surge up to 1100rpms and most recently, at 1500rpms and stay there.  I read a thread that said to disconnect the MAF to check if it was bad. It took a few starts, but sure enough the idle is at ~700rpms. Sure I have a CEL, but beyond that, it is safe to drive with the MAF disconnected? I plan on cleaning it before I dish out $ for a new one. Your thoughts please.

Hey there David, I have an extra MAF, o2 sensors etc. Bring it by the house tomorrow and I'll help you troubleshoot it.
Edit; whoops! Just remembered you have an m42 which uses an AFM instead of a MAF, so I don't have a spare but I'll still be happy to help you out. __________________ 4 MORE YEARS BABY!!! | | | | | 06-19-2008, 04:12 PM | #3 | | Senior Member Join Date: May 2008 Location: Oxnard, CA - SoCal Posts: 258 |

Not having it connected will mess up your A/F ratio and your gas mileage will suck. | | | | | 06-19-2008, 04:28 PM | #5 | | Senior Member Join Date: May 2008 Location: Oxnard, CA - SoCal Posts: 258 |

x2 on what Viper said...
Replace it ASAP, or you'll just end up spending it on the extra gas.
And im sure its not fantastic for the motor either for any long period of time. __________________ 11/97 Base  328Ti

where's the best (cheapest) place to get one? | | | | | 06-19-2008, 09:08 PM | #10 | | Senior Member Join Date: Aug 2006 Location: maritimes Posts: 1,433 |
probably Bavarian Auto Recyclers ( on ebay )
Most of their postings are "Best Offer" sales... ive got parts for less than half of their listed price that way... and they offer warranty on almost everything they sell.
I bought 2 front 328 calipers/carriers with 6mo warranty for $50 + shipping __________________ 11/97 Base 328Ti

i took the liberty of looking one up for you... http://cgi.ebay.com/ebaymotors/BMW-A...spagenameZWD1V Buy it now is $75... offer them $35-40 and I bet they will accept it.... Providing its the one you need anyways. Oh, and if your not a regular with Ebay... simply sign up, submit your offer and you can call their toll-free number with a credit card payment instead of using paypal or whatever. __________________ 11/97 Base 328Ti

Newbie question here: Where exactly is the ICV on the M42? A picture is worth a thousand words.... Can't wait to get my Bentley Manual. | | | | |
