2007 Honda CR-V, automatic, 230,xxx miles.
It's been having issues with throwing lean codes left and right for a year or so now but lately it's gotten real bad. The check engine light has been on consistently for a week now.
When idling my car the RPMs will slowly fall until it sounds like it's going to stall out then it "catches" itself and the RPMs go back up for awhile until it does it again.
My MPG lately even with lots of highway driving has been averaging 16.5 to 17 and I usually get about 25.
My car used to burn almost an entire quart of oil every thousand miles but since I've switched it to 10w30 I only burn about 1/2 to 3/4 quart during the entire OCI.
I did have a vacuum leak that was bad enough that my car would stall out in gear coming to a stop or taking a turn slowly but that's been fixed over a year ago.
I've already had the intake decarbonized, I've installed a new maf sensor and air filter, verified the O2 sensors are good and that there's no exhaust leaks.
Before I pay for a diagnostic could anybody give me a guess on what may be going on now?
