Saturn Ion Check engine light / startup problems Sign In

I have a 2007 Saturn Ion-2 (2.2L), automatic transmission, with 56k miles on it. Recently the check engine light came on. I took it into the repair shop and it came up with code po 2440 "secondary air injection system." He believed he knew what part had the problem and ran a test on it. Several tests. He couldn't get it to fail. He reset the light and told me to drive it for a couple days to see if it came back on.

It did. So we planned to get it replaced soon even though he couldn't get the part to fail in shop. End of story...but not...

Here's the current symptoms:

1. After driving for a bit and stopping briefly at a store (5-10 minutes tops), when I come back out to the car, it will sound like it starts up ok but it won't really start. The battery light comes on and you can't put it in drive.

2. After turning it off and starting it back up, it cranks very slowly but does finally turn over.

3. After resting for a half hour or more, it seems to start up just fine.

4. The car also idles strangely. After about 5-10 seconds, the car will give some strange vibrations/shudders that cause the whole car to rock. They go away as soon as you hit the gas pedal. This was happening BEFORE the startup problem.

So my questions:

1. What do you think this start up problem might be?

and

2. Do you think that whatever is causing this startup problem could actually be causing the odd code and therefore the part the mechanic thought was bad but couldn't get to fail could actually be ok?

Any thoughts are helpful. I'm taking it in tomorrow but I want some idea of what might happen. The repair for the first part is already supposed to cost me $438!
