hey all..
just got a 91 v6 a coupla weeks ago, and its givin me crap..
first off: im tryin to change out the fuel filter, but in order to drain the lines i need to cutoff the fuel pump when idle. but my fusebox has the lettering stripped out so i dont know whats what. anyone got a fusebox diagram? my email is ian.azeredo@villanova.edu.
also, im havin some problems startin and idling. starting- the car turns, but wont fire up unless the accel is pushed for a little while. it works when the air is cold. i figured this was the iac motor, so i changed that. but im still not getting it right. it has a high idle of 1500-2000, and occilates randomly between the two. im baffled. on idle the car misfires slightly, but more and more as time progresses. its like an increasing rate of rough idle.
anyone have any ideas?
im taking off the throttle and cleaning the airways. this might help, im kinda thinkin im not getting enough air on idle.
thanks

help!!

out with the old filter, in with the new! it needed to be done, but it didnt fix the start/ idle problem.

i took out the throttle body, cleaned the grime out replaced the icv, and even ported the icv airways. and great! the little engine that couldnt did, or at least, for a little while. the cleaned and smoothed out airways helped at first,,, but now its back to square one.

so now what? does anyone out there have any ideas? im thinkin pcv, or vaccuum leak, but im not in the wallet state of mind to start throwing parts at it.

the car won't start without a little coaxing at the pedal, and idling gets worse at stop at an increaing rate...
