ilde and missing problem
hey guys im new to this fourm and i have an 98 expedition xtl 5.4 L triton
its ilding rough and missing under exceleration but when i give it alot of gas it wont miss
i have done some searching on these fourms and understand that it could be a vacume leak or a coil problem
i do hear a loud hissing sound which sounds like a vaccume leak but i cant seem to find it
the sound is comming from the back of the engine near the fire wall
to me it seems that the sound is coming fron the pvc hose area but i have checked it and didnt find any leaks
is there a particular thing that with crack (plastic) that is part of the vaccume system??
also where can i find a online manual for my expedition??
thanks in advance
