I am not sure.... but any vacumm leaks can cause runability problems, so take off the cowel and closely inspect all hoses.

Poor Idle, stalling and poor drivability can be caused by an inoperative vapor management valve, damaged canister,split or cracked hoses or hoses conected to the wrong ports

Would this/could this apply to a 1999 Windstar? If so, how much was this part? Did you replace just the part on the firewall or is there more to it? I can't seem to find the exact part in AllData on this one.

Thanks, glad you got this taken care of.

All I had to do was take the piece that snapped off out of the rubber boot that connected to the evap on the firewall and then shove the hose back into the rubber boot, so I did not have to replace any parts.

the 99 engine is different from the 98 slightly but I would think the same parts are used there, I think the upper intake and lower intake has some differences
