2009 saturn outlook @ 150,000 miles on the clock. No CEL
My mom’s car is hard to start (takes a few tries) after getting gas. Once it starts it runs a little rough for a few seconds then again runs perfectly until the next fill up. During these first few seconds I find it keeps the engine from stalling if I rev up the engine a little bit.
I’m not a mechanic but I’m inclined to assume EVAP purge valve or at least something EVAP related. Is this reasonable? She’s been asking me about a fuel filter. If I drive up a hill or peg the accelerator to the floor it seems to have no problem keeping up, it doesn’t seem like a fuel restriction to me or at least not one significant enough to effect performance. I’d think if the filter was plugged it would be plugged all the time and not just during fill up.
It sounds like you’ve probably diagnosed the problem. Purge valve problems are fairly common posts here. The forum search feature will show you what others here have said about that topic.
