I know you just replaced the throttle body, but did you ensure the flex pipe isn’t leaking? The intake manifold isn’t damaged, like where the brake booster hose fits onto? Are you sure, the fuel pump isn’t the problem or the fuel injectors, this list is from OBD II codes.
Possible solutions include: Inspect all vacuum and PCV hoses, replace if necessary Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect fuel lines for cracks, leaks, or pinches Check the fuel pressure at the fuel rail Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced. Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem)
