Fix the misfires. What cylinders? I suspect you still have a problem with the timing: review your work.

I really cannot stand PMs. So you checked and your timing is ok. Good. Let everybody know, so you can get advise on other possible issues. Start with looking down in the crankcase to be sure you haven't dropped something. Years ago, a guy had an issue because his rag was left in the head when he buttoned it up, rag got sucked into the engine (left side issue) and clogged the oil pump. So you need to keep looking. Most of us are here to help, only if you share what you have done.

Rant complete!

I have updated that with pictures in my other thread I will not start the car until I get endoscope to check if there's broken plastic I'm sure there's some pieces.

I had multiple misfiring and the engine was vibrating and not smooth the obd reader did show misfiring in cylinder number 4 and 6 I replaced the coil number 4 with NGK ignition coil and changed the spark plug in that cylinder too with ngk spark plug for the cylinder number 6 I used eBay ignition coil but the coil boot on the eBay coil was too tight I think it wouldn't fit the plug correctly I removed that tight coil boot and used the coil boot from my old denso coil tightened all the bolts of the coil then start the engine the engine run smooth. btw the coil is 4 pin
