Cleaned MAF sensor and throttle body, replaced plugs and EGR valve
Ok I need some help! I have a 2010 Ford Focus sedan. Bought in march. My check engine came on with a code 300 . The car ideal rugs wacky, all over the place. As I drive it feels like it is going to stall out , it actually has a few times. We haves the spark plugs and it wasn't the issue . Where should we go from here ?
Ok did you check for vacuum leaks,is the fuel pressure gooddid you change your air filter,did you check around the intake manifold for vacuum leaks,is the engine missing if it is do a compression test on the cylinder thats missing you may have a burn valve or one that is not seated properly check you cam lobes also if the timing chain makes noise change your chain and tenssioner

dont take soo much in consideration after you have make all this things, some time is on only for any wire faulty, or a shrt electrical arc in any place in wire system. ask auto tap mechsnics for this maybe they have similar case before.

If engine is actually running lean,could be clogged fuel filter or weak fuel pump.

There is a large vac line coming straight down from the throttle body that goes to the PCV system. See if it has a hole in it. It is likely sucking air.

Hi, have you checked your intake manifold gaskets for a leak? If not, start the car and spray carb cleaner on the gaskets, If the engine speed changes, you have a leak. Also recommend you verify the throttle is closing fully. please let me know if you have questions or need instructions for changing the gaskets.
