this is what happened...

while changing intake gasket, the rubber T that connects the vacuum lines broke and so i rigged a new one <- might be the cause
when pulling out fuel rail and injectors, some wierd plastic piece on bottom after the o-ring broke. no leak cold be found.

right after the intake gasket change, ran car for a good 40mins with no engine light. this mornin it comes on. also got a clicking sound coming from alternator. think i need a new one?

please help me with this retarded P0171 code
 


i replaced these vac lines and both T's.

and the line on top of the TB was cracked as well. so i used a fat vac line to a smaller line that would fit inside the fat line, then to the plastic stock line, this line runs to the evap off the back of the sc.

can u tell me where that hose goes? perferably a from - and - to pic
 
that vac lines goes inside the cars cab to the dash. it controls the fan directions. huge vac leak lol.

look behind the engine for it, thats where i tossed mine when doing the lim gaskets.
 


it did! for 40 mins straight. but the idle seems lower. idles at 900 instead of 1200. also if i rev it to 2000 or 2500 and release peddle, tach goes to 1500 and idles for 3 secs and slowly goes to 900
