07 won’t stay running without acceleration
I have a 07 CX seven 130,000 miles. Getting code P2177 and P0300. The engine will not stay running unless you hold your foot on the gas up to about 2000 RPMs. As soon as you let it off the vehicle will die every time. This all started after I did a sea foam intake cleaning. And an EGR valve/tube cleaning. The vehicle is notorious for carbon buildup I’ve never had an issue after cleaning it like this. I’m assuming all of the carbon or something that was exiting the engine may have clogged the O2 sensor . My wife likes to run the gas tank completely empty every single time as well so it could be fuel pump related. I’m at a loss. If anyone can help me and point me in the right direction this would be greatly appreciated.

Any help would be greatly appreciated. It’s been sitting in driveway for 2 weeks now. I can drive if I manipulate the throttle and use manual. But it’s still very sluggish and if you floor it. It bogs down.

you might want to retrace your steps with the throttle body and egr. the code indicates too lean which means too much air is coming into the system causing the ecm to go into fail safe. air seeping in at the throttle body or some part of the air intake. look for any unconnected vacuum hoses. recheck the egr for seating correctly. and lastly pull the upstream o2 sensor and spark plugs to see if it got coated with gunk from the cleaning. usually not the case but like you said these engines are nortorious for carbon build up and perhaps your cleaning shifted things around instead of sending it out the tail pipe.
