I took it to Pepboys and the lady said "P1140". Thus my thread on P1140 elsewhere. I got my reader back and it was P1130, Swirl Control Valve. Glad I didn't buy the Cam Position Sensors.

This valve sits right up on top of the engine but some reading told me that it is sensitive to a lot of inputs. I had just replaced the spark plugs and the idling improved greatly and I thought maybe it just needed to remap to the new idle conditions. I reset the code but it came back in about 150 miles later.

Next some reading told me to blow out the vacuum lines with air--they get clogged up. I thought that was very unlikely but free so I pulled the first one off and tried to blow through it with my mouth and was greatly surprised. No flow. Same with the 2nd long one. The short ones weren't so bad. I blew them out and put them back on and so far 300+ miles, no SES light, and gas mileage the first tankful seems to be 2-3 mpg improved.

I'll post further updates if anything changes but blowing out the vacuum lines is free and if it really gets you 2 mpg, everyone should do it whether they have the code or not.
