ok, so tonight my check engine light came on.
I pulled over, and scanned for codes using my scanguage II, and the code thrown was P1174.
for an 08 it says its "Fuel Trim Cylinder Balance".
Not exactly sure what this means.
anyways, I cleared the code and and continued on my way. I was about 20 miles from home when this happened, and the check engine didn't come on again.
I have noticed that my economy isnt as good as it usually is. I usually get around 37 MPG @ 55. it dropped to 35 MPG.
I use the unleaded plus (kwik trip)for gas, and haven't had any problems till now.
about two tanks ago, I tried "sea foam" and didn't seem to have any problems.
Is this something i should worry about? something i should have the dealer check out? I'm sitting at just over 30K on this car.
