Stumbling and hesitation...

Ok, I'm sure this has been beaten to death but I'm new to this motor and need some advice. Alright, it's the 2.0 n/a motor 5 speed. When motor is cold, I'm getting serious hesitation. I'm having to floor it to keep it going. After it warms up, that issue kinda goes away and only have a slight stumbling upon part throttle. Engine code was p1128 saying running too lean. I know it's not my MAF, been tested and passed. I checked all the vacuum line visually and with spray at idle, nothing. I'll have the code cleared and it'll stay off for about 50 miles, then it's back on. The issue with hesitation and stumbling happens if the CEL light is on or not. I've read a ton of threads over this issue but have yet to see the correct solution. Read from o2 sensors to MAF to fuel filter....thanks

Could be that the CAT is clogged causing issues with proper pressure or somewhere in on your muffler parts you are losing pressure.
