here is another probelm, every once in a while for months now i would also get a p0170 and p0172 code and when i reset it it would take a few weeks to come back. ever since i changed the fuel pump to the walbro 255 i cant go a day with out it comming back on. what do you think?

p0172
DTC Definition: System Too Rich (Bank 1)

p0170
DTC Definition: Fuel Trim Malfunction (Bank 1)
both codes are always together when the light comes on.

this is a noticable hesitation and im not spraying anything, this is basically a stock b16 engine. to make this easier lets just consider this a stock 2000 honda civic si.

it could be maybe that the stock FPR makes the car run a bit rich with a 255?
