Is the GC getting enough carrier gas pressure to maintain the set flowrate when the oven heats up?
I'd figure out what the max injection port pressure is that the method needs. Then set the inj port pressure a bit higher than that, and make sure it can reach that setpoint.
It is a column flow constant method. The flow is 1mL/min in all the chromatogram and no trouble exist in the flow.
