Perhaps, but it would leak all the time and not just sometimes. Also, it would lead to very messy running (uneven AFR across cylinders). If I disconnect MAP, ECU is able to compensate and AFR goes bang on to 1.0, so it is probably not injector.
My bet right now is fluctuating fuel pressure. Fuel return/filter might be clogged so fuel pressure briefly goes above what can be compensated by computer and it registers error code.
I have new FPR/filter assy but it is placed in the most awkward place possible: under the car, on the top of fuel tank.
