tank. The codes are as follows. P0325 (knock/combustion
sernor 1 circuit bank 1 or single sensor)
p1505(manufacturer specific code) p0446( evaporate
system vent control circuit) p0301/p0303 (misfire cylinder

Evan issue or a fuel pressure issue. Thought??? Any help

Flashing light means misfire which you have. the evap leak could be a vacuum leak or a stuck open sensor causing a vacuum issue giving you the misfire.

@cjsras, right, but the"misfire": goes away at 1/4 tank. @f_o_r , yeah easy place to start.

Unsure if it really goes away, the cel just stop flashes at that point. So from a full tank to all the way below the 1/4 mark on the gauge it flashes then below that it stops, at this point it sounds like you’ll think I should start with the evap system, these still have the test mode under the dash do you know? I’ll look in the Morning.
