My girlfriends car(2001 Gp GTP) has been stalling out constantly and I can't find the issue. When it stalls out it takes some time to start up and when it finally starts it dumps black smoke. So far I've replace the crank sensor which prolonged the time between stalling, but its since came back. So i replaced the TPS and MAF due to the codes being thrown after it stalling....again it prolonged the stalling but it came back. So i went over all the vacuum lines and replaced the cracked ones and then the car went several days without stalling, and now its back again. I'm at a loss on what to do. I checked the fuel pressure it has good pressure(43psi) and even when it stalls out the fuel pressure remains at 43.
Disregard the posts below, I erased my old post and typed in the info above.
