I’ve got a 2012 Eco with 60k miles that up till recently has been a solid and reliable car. Mileage is consistently in the high 30’s. Couple weeks ago, I noticed power loss on the highway and had to downshift to keep the RPM’s up as this was the only way to accelerate. At low RPM’s, the car would stutter and I’d have to get into 3K+ RPMs to move around. It felt as if the turbo died. No CEL.
The next day, I noticed a puddle of oil under the car and lots of smoke coming out of exhaust when first started. I found that oil was leaking from the throttle body and drove to the dealer for diagnostic and repair. The dealer confirmed a PCV problem and replaced the valve cover, cam seals, and water pump.
The oil leak was still there over the next couple of days of driving so I took it back but now the CEL was on as well showing P0304. Plugs and coil pack were replaced but the code keeps coming back. Dealer claimed that leaking oil was residual and did some additional cleaning.
The oil leak has stopped. I cleared the code but it comes back in ~50 miles with the Stabilitrac light. The Stabilitrac light comes and goes but the CEL is now constantly on. The CEL flashes at times. My next steps involve taking the throttle body off and cleaning it thoroughly. Any other ideas? The car drives fine and besides the CEL light, I believe the MPG’s have gone down but I won’t be able to confirm until a few more days.
