I just had my coil pack replaced. .. .i had a misfire in #8 then random misfires. .. i changed the #6/8 and it didnt make a bit of difference. ..
before that i thought i had a fuel leak or a leak in the air intake.
if i was stopped at a light, the rpm would move up and down slightly. . the car would act as if it wanted to leap forward. and sometimes it would just cut off at a light so i would keep it in neutral . . .at one point. it would take me 4 or 5 tries to start it up. . i changed the fuel pressure regulator then it worked ok for a minute then back to the same. ..
anyway turned out to be the whole coil pack that needed replacing

what about the fuel pressure ???
will try to assist you but your posting was cut short for some reason. i got that it will crank over and over before it starts. and something about your fuel pressure. ok. your fuel filter may need replacement,but in meantime try this: try turning your key switch to the'on' position three times for 10seconds at a time before you attempt to start your engine. if the fuel pumps weak,this will allow your engine to'prime' with fuel before you start your engine. it really sounds like your fuel filters going bad,or stopping up,or the fuel pumps weak,or your fuel pressure regulators not working properly.is your check engine kight on? your local autozone or advance auto parts store can check it for free,as long as your check engine light is on. thank you for choosing fixya.com let me know if i have assisted you please.
