So I just bought this thing for my wife, I wasn't going to except he came down enough on price it was hard to say no. And since her Captiva got totaled... anyway so the first time it happened was coming into our driveway at low throttle it started surging like you're patting the gas, and then just died... well after I picked my heart up from my stomach since this is the second day I bought it and just had new tires put on it, and changed the spark plugs that were probably never changed. Put it in park and it fired right back up... okay that was not good... but drove fine, up and down the road afterwards so I figured I'd go grab my scanner and....well I can't find it soooo I head to Advance Autoparts and just had them scan it, got those two codes... I will say the P0171 MAY be my fault. When I changed the spark plugs, I forgot the plug the PCV tube back into the inake "box" / tube... It had been driven maybe 5-6 miles without it but not hard just normal. Right before it got scanned literally in their parking lot (thought about it as I was headed there) I popped it back in. So that MAY be a code that was thrown due to the un-metered air coming in, it could have also been per-exsisting.

The times I have had a clogged fuel filter or something the engine would just run rough.... I have searched and can't seem to find online anyway a fuel filter location? Is it the typical silver cylinder GM fuel filter that's been used for decades (well up to this thing anyway) Also it looks like maybe it's direct fuel injectino instead of EFI? (port).

The main and most alarming thing is this is my wifes car, and she will have our kids in it, so it can't be just dying unexpectedly when going to accelerate from a stop. Could either issue cause this? And how screwed am I on the cam sensor thing (P0010)?

 

Well with some more searching on the web I figured it out. I ended up causing that lean fuel code.. my fault, gone. And the P0010, I replaced the solenoid which luckily is super easy to locate and change. I was worried it was going to be in the block on the back firewall side or something and be a total PITA, but nah. Code's gone, car runs much better now.
