Question got acceleration problems!!! help me pls!!

Ok, my laptops took *****, so i dont have anything to log right now, but here's what happened. I put some bosch o2s in a few days ago. The car ran fine, but there have been somethings really pissing me off!!! Ok, I was pulling out of my apt's. Made it to the stop sign right at the corner and went to make a quick right since there were cars coming. it was in first gear and i gave it some gas and the damn thing was just chugging along, it would barely move at all!!! This has been happening a few times here recently! If im in 2nd gear and punch it, again, it just chuggs along, it feels like it hits a certain point and then nothing. The car has been chattering worse than ever also. I have a thread in the handling and braking forum on a seperate issue, but im in the "i just wanna get rid of this damn car" phase right now pls offer me your suggestions and ideas...i know i need a laptop, but bare with me till i get a new one.

they're new tr55's. they went in after the install. i need to wait a few days, but i think i found a IBM laptop that will suffice as a tuning laptop. Its a good thing i saved all my logs and bins to my thumbdrive! Tomorrow, im going to also order a few suspension bushings to replace to help with some of the mechanical issues im having.

if it was a misfire you would feel it under high load a lot, through the whole rpm range, if yours is specific to an rpm range i woudl think bad spot in the VE table. does it do it all the time? no matter what the operating temp?

You running cats? Could be a clogged cat, but that usually gets you an SES light.

Has it had that problem since the new heads/cam ? Have any of the tuning changes you've made made it better/worse ?

So no SES lights on the dash (or flashing ?) when the stumbling occurs ?

Do you still have the stock MAF ?

yes i have the cats, but i dont see how it would throw a code if none of the emissions are connected or there being any rear 02's. It just started happening not too long ago. it happenes no matter what rpm or ect im at. the car just stumbles hard. I think my mommy is gonna get me the most basic laptop dell has to offer to get me by :yay: I hope!!!!Ill check the plug wires in a bit. any other ideas??
