I am experiencing somewhat sluggish acceleration. Not bad, but noticeable. The engine sounds louder at idle, no rough idle (that I can tell), but louder.

The codes I get are P0135 (most common), P1133, P0155, and P0134. I clear them and I can drive maybe 30 minutes highway and the P0135 returns all the time. The other codes are intermittent. I recently had my fuel pump replaced, but this issue existed before my old one died. However, when the fuel pump was replaced, I have been noticing a gasoline smell. The repair shop that installed it said it may be normal. Please assist

    On my car, the codes can be cleared by disconnecting the battery or resetting from the dash controls. Both have been done and the situation above exists.
