Need help!!!!!

After engine replacement CEL came on and blink for about eight times when I turn on the engine and then stays solid for about a minute or two and then start doing the same process again so that cause to lose power and sometimes turn off when I’m coming to a stop or a red light I have done a diagnostic test in three different places and they told me the same thing that there is a misfire on cylinder one so I did a tune up but the car still doing the same so I changed the first ignition coil thinking that is the cylinder one and put it on the third one but the problem it’s not solve.. Do I need to replace the all ignition coils?… any help, suggestions or comments would be very appreciated

first off, what code are you getting with the CEL?
I'd recommend that you change all plugs/ coils at the same time. It's not mandatory, but it's the most effective and efficient, imo.
Also, maybe check your cat. It could be toast?

I would say if the 20 brake pump doesn't work then your friend did something wrong.

where you "got" the replacement engine anyway ?
