Starts happening last night on the way home. I gave it gas and it would very slowly pick up speed. It is chipped with giac stage 1, 93 octane tuned. Has apr r1 DV. This morning heading to work did the same exact thing, it is getting anoying and would appreciate if someone could help me out.

 

Are there any fault codes stored?

 

There was 2 codes, MAF and O2 sensor. But the codes haven't came back on yet. I will post a video when I get a chance.
