Hello,
I hope this hasn't been covered but I couldn't find anything.
This has happened twice. If my 850 idles, even if its only 5 mins max, it wants to stall out once i put it in gear. Tonight, I pulled into a spot, put the car in park, talked for a few mins, when I put it in reverse it almost shut off. I gave it some gas and put it and drive and it almost died again. Once it drove for a few feet it seemed fine. I didn't get any codes. Thanks for any help.

 

If you have NO CODES my guess would be fuel pressure.

 

hmmm. damn, I have an extra relay at the house. Ill see if I can get a fuel pressure gauge and test it this week though
