I should have mentioned, I'm paying them for a diagnostic service, I did troubleshoot the MAF, and told them along with the other things I had done to try and isolate the problem. They came back instead of saying "your MAF is actually bad" or "you have a vacuum leak" and said &qu...

Well I took out the IAC and gave it a cleaning (it wasn't too gunked up) and the problem persisted. I took it to a shop to have it diagnosed and they responded with... "You need to replace: -the MAF meter (which I'm assuming is the sensor and housing?) -air filter -vacuum hoses -flame trap serv...

Oh that is a great link, thanks jreed, and for the original post as well. Definitely going to give that a try when I have a next free day. In your og post you said you used MAF cleaner but it didn't work too well. I have some, but do you think it is even worth using it? Or should I just go buy some ...

Oh awesome, thanks for the appropriate link erikv11. I'll check it out when I get home. Hopefully it's just a loose hose that would be great.

Cleaned MAF, as well as removed it to see if it would stay running, with the MAF disconnected it still does the same things. I pu...

Hello all, I just flushed my coolant, replaced with Zerex G-05. However, when I was burping the system the check engine light came on. There appears to have been a sizeable bubble trapped in the system somewhere, because it took quite a while for it to surface. By the time the reservoir needed to be...

Great, will try this out. Thanks.

Hello, This winter I've noticed something peculiar with my 850. The first time I drive the car, say, in the morning or after having been stationary for a while, the RPMs will drop to ~500 or even lower after the first time it reaches 3k. If I shift out of 1st and into Neutral at around 2k, if I reac...

Hello, I'm planning on flushing my radiator and refilling with Zerex G-05. However, I was wondering if it was a bad idea to use the Prestone "Flush" fluid in addition to distilled water after the old has been drained and before filling with the new? Or should I just use distilled water and...
