Check your fuel filter.

Disconnect and then reconnect your battery will sometimes work...it might be worth a try.

Ok, what is the question? Get one and replace it.

Did you fix this issues? Did you replace the PCV?

OD is over drive for your transmission,it's also call a passing gear,when ever u go to pass someone and u get on the gas that is your OD kicking in it just regears your tanny there should be a button on the dash or on the steering column to turn this off,it shouldn't hurt your car you will just burn more gas

Any codes?Do you have gas?Is Battery is OK?mean crank power.

Neither of those codes depend on a bonding strap. Replace the MAF and the knock sensor.

There are some possibilities which you will have to check in this case:--
1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.
2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.
3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.
4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.
5) If all the above possibilities mentioned above checked out OK/perfect then it’s a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Have the fuel pressure checked first, then with those results you can decide if low fuel pressure is the cause. You can also have a plugged catalytic converter.

if it was a clogged cat i doubt it would go over 40 at all or even reach 40, needing a gas cap won't make it lose power but a bad 02 can cause some issues with the fuel mixture and that can affect performance, do you check to make sure the transmission is starting off in 1st gear?

Oil leaking "in" your valve cover? Where is the oil at/coming from? And, to answar your question, rear main seal is a real job! Requires removing transmission, flex plate/fly wheel! It is the crank shaft seal, on the "rear" of the engine!
