06pilot

Im praying someone can help me I have a 06 honda pilot I removed the top plastic cover by the tensioner belt to feel if there was play on the timing belt which indeed there was. Then I loosened up the serpentine belt . Per a video I watched then I took off the 19mm bolt to the harmonic balancer...

When it starts idles really rough, and when i put it in gear it dies unless its completely warmed up, check engine light and vtm-4 are on and blinking it says all my cylinders are misfiring, also its smells like antifreeze pretty bad, I need help.....
