I have replaced some parts like fuel pump and filter assembly, camshaft and crankshaft sensors, PCV valve, spark plugs (Bosch Iridium ones)

Speaking of labor and costs... Shop is charging me $1400 bucks, parts & labor with 1-year warranty.... Funny thing is the car was $1200 when I bought it

Thanks in advance for your opinions.

wait, what? how would valve stems cause a misfire? if it was leaking I would think you would get a consumption of oil and the CEL would be a O2 sensor issue.
why did you replace camshaft?
I can't believe no one noticed you used Bosch plugs. I would guess that is the misfire issue before anything else. you need Denso or NGK. even german cars run NGK. I've always had issues with Bosch plugs.
$1400 is a lot of money. you could buy a complete engine with less than 20,000 miles on it for like $700
