Codes P0351, P0352, P0353, and P0354 relate to ignition coil primary/secondary circuit malfunctions. Check the wiring and connections to the ignition coils, ensuring they are properly connected and free of damage. Verify the coil packs are securely seated. The black and wet spark plugs suggest a rich fuel mixture or incomplete combustion. Inspect the fuel injectors and consider checking the Mass Air Flow sensor, Oxygen sensors, and the air intake system for potential issues affecting the air-fuel mixture.

Uh oh, sounds like your engine swap in that 2008 Camry hit a bit of a snag! Don't worry, engine swaps can be tricky, even for the most seasoned gearheads. Let's troubleshoot those pesky codes and get your new heart thumping like it should.
First things first, those P0351, P0352, P0353, and P0354 codes are all screaming "ignition coil malfunction" for cylinders 1 through 4. This, coupled with the black and wet spark plugs, tells me we're definitely dealing with a fuel-rich situation. But before we start throwing parts at it like confetti, let's break it down:
You may need some parts in the process, click this link to be directed to our website where your vehicle information has already been entered. Simply enter the part's name into the search field to get started.
One last tip: Keep those new spark plugs handy! With a rich-running engine, they'll tend to foul quickly.
Good luck getting your Camry back in the game!

- Double-check those connections. You mentioned you checked the grounds, but did you do a super-thorough double-check? Even the smallest loose ground can wreak havoc on the ignition system. Trace all the grounds related to the coils and engine control unit (ECU) to make sure they're nice and snug.
- Coil culprit? It's possible one or more of the new coils might be faulty. Swap them around (following the firing order, of course!) and see if the misfires follow the swapped coils. If they do, bingo! Replace the bad boy.
- Sensor shenanigans. Did you transfer all the old sensors from the previous engine? Faulty sensors, like the crankshaft position sensor or camshaft position sensor, can confuse the ECU and cause misfires and rich running.
- Fuel pressure frenzy: Black, wet plugs can also hint at a fuel pressure issue. Check the fuel pressure regulator or injector seals, as excess fuel can overwhelm the cylinders.
