Sputter / Bogging Problem

amy

2005 stock srt 4,  Car recently started sputtering/bogging out under acceleration.  I have replaced spark plugs, wires, ignition coil, crankshaft sensor, and cam position sensor, and problem still there,  What else can this be? getting code p2305

Could anything have made your fuel filter really dirty?  Did you move any intake piping and develop a boost leak?  New Spark plug wires fully clicked on?  Is fuel/gas in your area oxygenated this time of the year?

Do you have any cel codes from the check engine light flashing?

Nope it just flashes and goes away, when I check no codes come up

Flashing CEL means a missfire (usually won't throw a code). Plugs, wires then coil in that order first (USE DIELECTRIC GREASE!!!). Then move on to bad gas, dirty injectors (injector cleaner), fuel filter then fuel pump in that order.

Ill try cleaning the injectors and look at the fuel filter,,

it starts and idles fine

Mine started and idled fine but until i got into boost it sputtered and ran like crap checked out coil pack come to find out it cracked under heat and which caused it to fail start cheap as north said dont assume the worst.

Ok ill check it tomorrow morning

Easy way to check the coil and wires for cracks is spray mist water on it, if it starts to short out then you know there's a problem.
I had a similar problem with sputtering in high boost and I just used dielectric grease on all the secondary ignition connections and haven't had a problem since

spray over the coil with car on? please explain, i shall try it tomorrow

i had the same problem , when i bought my car it would miss up top but that was becaused my plugs had a gap of 55...bought new plugs and gapped to 32

i have a question...my car idles fine. just below 1 where it should. when i accelerate in first everythings fine, but when i get into second it seems as if i have turbo lag. ALSO ive been noticing that when i let off the gas, my car wants to go and it feels like its pulling its self. bent valves? fuel system? injectors?

Mine started doing that yesterday (sputtering/bogging) regardless of the amount of throttle.  
Installed new coil pack for $80 from AutoZone this morning and it's back to normal.

i also have been noticing that when i take turns at around 30 or 40, like taking and exit off a highway, i hear a grinding noise. bearing shot? tie rod?
