Hello, I recently had a condition of no start after refueling. I replaced the evap purge valve and that fixed the no start problem. At the same time I changed all the plugs and coils as well. Now I'm getting the low flow during purge when I reach a 1/4 tank of gas. The c.e.l. stays on until I clear it and then stays off until I reach 1/4 tank again. My car is a 09 cts4 with the ly7 motor and 100,400 miles on it. I do not have any symptoms that I notice while driving other than the check engine light.
