'01 B5 A4 1.8t with APR 93 chip otherwise stock. 122K on 

Been running fine, no changes except for a new MAF a week ago.

Accelerating to highway speed today my engine suddenly started 
running rough. At first it felt like I hit the rev limiter 
(nowhere close), check engine light came on (flashing) and codes 
showed "intermittent engine misfire."

Anybody seen this before? It feels like either a spark or fuel 
issue. Idles okay but has no power and is rough under any load.
