[QUOTE="DropSVT, post: 15572190, member: 180537"] Hey guys I'm in need of some help. I've done numerous searches and can't find anything groundbreaking on my problem. My problem happens after I drive the car for a bit and turn it off. When I start it back up it hesitates, stumbles, runs lean enough where my wideband can't read it, and is at -10 vac instead of the average -18 on the ol' boost gauge. After about 5 minutes of letting it shake around it clears back out and drive on like nothing happened. When it first happened It was only after 5 min of it being off and I thought I had lost my pumps and needed a tow. Thought maybe because I was on a slope it lost its gravity or something but i was wrong when it happened again the other day after parking to take some pictures. Does anyone have any ideas as to what's causing this? I replaced my o2s in August and thought it could be those but I'm not sure. By the way I can hear the fuel pump when I turn the key on so I know those are working currently.
