Check that you fitted the accelerator cable correctly or connected up the electronic accelerator motor cable to the manifold throttle.

SOURCE: gas pedal unresponsive
Try this: Go to your local parts store and purchase a can of (throttle body cleaner) you will take your air filter out and remove the big tubing that is connected to your throttle body and filter housing. Spray the cleaner inside the throttle body, open the (butterfly) and spray around the pivot the butterfly opens and close on. What happens is you get carbon build up in these areas and it causes the gas pedal to feel like it's stuck and have to apply more pressure to the pedal. You will see alot of black carbon run out of the throttle body. Take a clean rag and wipe down the area of the throotle body. Repeat the cleaning 1-2 times. put your air inlet tubing back on and re-install your filter. It may seem hard to start at first but it's drying out the cleaner that was sprayed inside the body. Try this and see if this works. I've done this on many vehicles that shops want to charge $300 to do and all you need is $5 cleaner. It's very easy to do and takes 20 min.

Uhh there are no rods in the head. That dealer has a loose rod in his head maybe.
The crank, rods and pistons are all in the bottom end of the engine.
What it likely is is either a broken piston skirt or a spun rod bearing.
Spun crank bearings are rare and sound deep.
A spun rod bearing can be fairly quiet on idle depending how bad it is worn out, but it will be really loud on acceleration. Piston slap from a broken skirt can be pretty loud too but it mostly sounds like diesel rattle only a bit less. Some have described it as a loud pinging sound like detonation.
Drain the oil and check for metal debri. If you can tilt the vehicle a bit for the oil to drain more towards the drain hole that could help. Then look for metal pieces and judge their size. There should be NO glitter whatsoever in engine oil, or any kind of debri. Now a rear end or transmission is different. Those always have a little metalic sheen to them.
Best of luck.
