Studdering under boost and cruising

[JBDdsmer610]

well i noticed the other day my car started idleing weird almost like a miss fire thought nothing of it. well it has gotten worse. i have no boost leaks what so ever running all stock IC pipeing. when im just cruising not boosting at all the car is studdering real bad then i start to boost once i hit like 10psi at like 4800rpms the car feels like it hits a fuel cut or something. When im just driving in a parking lot in like 1st or second at low rpms the car bucks real bad. i cant figure out what the problem is......HELP ME!!!

Long shot, but have you looked at you plugs/wires...

my car would studder under boost and the plug gaps were all over the place.. up to 4 times the recommened, gapped them to .28 and the car runs great..cheapest fix ever

i was thinking somewhere along the lines of my plug wires i think its deff an ignition problem im gonna go pull the plugs now and take a look at them and check the gaps. and how do i go about testing the plug wires.

all my gaps are fine the one plug was a little losse but it didnt fix my problem

im still investigating this problem i've notice that it dose it real bad when i am at low throttle im gonna say mabey 5% throttle at like 2500-3500 rpms if i get on it it goes away a little bit but i can still feel the car hesitating...help me please!
And i am not throwing any CEL's at all

Buy a spark plug wire tester. Disconnect fuel pump when you do this so it doesnt flood. Its a cheap little tester with instructions, very simple. I am having the same problem but probably worse haha. havnt figured it out for a few months now.

thank for the input but i found my problem went down to my local dsm shop...(Ground Zero Performance) he's a good guy hooked the scanner up for me and the voltage for almost every sensor was flctuating and bouncing all over the place.....well let me get to the point. When my dad went to colarado for vacation he picked me up an ecu for my car ### i had an A/T ecu well ecu was fine when i got it pulled the ecu out of my car and the CAPS were leaking threw my A/T ecu back in and the problem was gone.
