2004 honda, lost power and sputters. Will crank with gas pedal to floor but not enough power to move car. take foot off pedal and it dies

You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It uses an idle control valve to adjust the idle speed. The valve could be dirty or failing, or the throttle body could be dirty.

try and clean the throttle body and throttle plate and the idle air contol valve

I had the same problem and it was the throttle position sensor. have you replaced this? Very easy and solved everything.

Check if all your ignition coils are firing!! Typical issues are: Sputter/****/misfire under load (foot on gas pedal), stalls, no spark. On these 5.4L, moist and other fluids tend to short the coil out. This is caused by poor design of the coil boots.

Sounds like you came apart under the hood. Check the linkage and on the drivers side there is a switch called a TPS. The throttle position sensor should have a spring in it. There should be some return action on the linkage too.

There is a cable that works everything from the foot pedal to the engine. If the cable is still attached it must have broken inside.

You pinched the fuel line????
If you crank for too long to start the car, the engine will "flood", this is why the plug was wet. It had too much gas and wouldn't start.
Pull out ALL plugs and dry them off.
Install them.
HOLD your gas pedal to the floor and crank.
This will stop gas from entering the engine.
you need to get that extra gas out beofre it will start.
If you have so much gas in there you can do damage to your engine!!
Now after a few crnaking attempts with your foot to the floor, take your foot of the gas pedal and try to start it again.
But remember if it doesn't start in 3 tries, you need to do the pedal to the floor once or twice to remove the excess gas.
When you crank the car to start it sprays gas into the engine, even if it won't start. So it very easy to "flood" the engine, and then you'll have a hard time to get it going!

u need a throttle body cleaning along with a complete chec of the whole fuel system-haynes repair manual is detailed

maf sensor or fuel pressure regulator

Local mechanic determined engine was flooded and started it by holding throttle to the floor and cranking 5-7 seconds - then the engine sputtered to life. It has run perfectly before and since and I'm at a bit of loss to understand why this occurred this one time - so far. It's been driven now 5 days with no problems.
