stalling at a coast update...

[BOOSH]

Hi I have a 1995 900se 2.5 that i recently purchased. Since then i did head gaskets, valve gaskets new plugs and wire, and a new belt. After i did the valve gaskets I will stall out a a coast upon investagation i found this yellowish tan line coming off my throttle body and i have no idea what it is or where it goes. Please help.... ps after i did the head gasket it was fine..it was not untill 2 weeks later after doing the valve gaskets............................

ok so i found out that the line was my fuel pressure regulator lol im a tard soo anyway the problem is still there...AND then i found this.. Anybody know what this is...a temp sensor or something is my guess.....

it was the coolant temp sender...and of course i had to buy the new housing that that was bolted into...so after a long bit of searching i replaced the coolant temp sensor, coolant temp sender, the thermostat adapter housing. She runs great now..i didnt know a coolant sensor could do that to a car...weird...but the day i got her fixed as i was on my way home i snapped my clutch cable :soo its just one thing after another lol..pics soon
