Coil plugs are around 50, @ Autozone or Orieleys .....or you can find a set of AF ones for around 300 give or take. that would include all 8 and thats what i would suggest if one of yours is faulty. i had 1 go out on me and i replaced it, then another went out a few weeks later...so i just replaced them all.
The injector cleaner or fuel system cleaner is under 10...Tps is around 30..anything else

 

i guess i will just try and do it myself, if not i guess i have the parts already and i can take it to a shop

 

I would suggest doing it yourself, its easy and plus if you go to the shop they are going to rape you!!!

 

i just dont want to make anything worse or do all this stuff and it not be fixed...

is a coil plug the same as a coil? i need a whole new #7 coil...

 

no need to pull the fuel rail, just remove the bolt that holds the coil to the intake and pull it out. i still suggest you find out what codes you're getting then post them up here before you do anything

 

cool, ill go to autozone and get my codes checked

 

fuel rail is not coming out. there are 2 bolts that are holding it in place, i removed those and pulled really hard on it but its still not coming out.... any ideas?

the fuel rail does have to be removed because the coil wont clear it when pulling it out...

 

ok i got all that figured out, but it didnt fix the problem...

it worked fine and was idling correctly for about a half mile when i drove to get gas and drove back. then when i got home and let it sit for like 10 seconds in drive, it started sputtering again. rpms would drop from 600 to 500 and then shoot back up and drop and go back up. what the hell is going on lol. where is the IAC and how do i clean it? someone mentioned that earlier in the thread i think.

i am also missing a hose clamp for my cold air intake. the one right above the MAF that has to be huge, could that be causing the idling issue?

 

that could be it!!!! leave it running and hold the rubber coupler tight,see if that helps, if air is entering from after the mass airflow sensor and the car is confused, constantly trying to fix the problem with more gas/air. try getting 2 or 3 hose clamps and combine all of them into one big one till you can get the right size.

 

I can't believe so many different things are being thrown at this poor guy...

First things first, don't start throwing parts, money or your free time at this thing.

Get the codes scanned, then promptly go home and install your factory air intake. Pull battery for a few, connect and drive. See if the symptoms persist (I feel like a doctor).
