I love my car i been fixing it for a bit my celica before I bought it, it was sitting for 3 yrs not running cause it needed a new pump well i put the new pump and it went out drop tye tank and it was rusted so i bought a new tank than i did a whole new front suspension new coil new spark plugs and it was still misfiring than just today I changed the injectors and now it’s knocking took them out and put back the old one and it still knocking. Found out why my car was misfiring 2 of my injectors was leaking i think I messed up my car and for the price i got it for it’s worth the fix until now i think 🤔
Wow whole lot of new info there. Did you check/change the oil?
Some debris may have fallen into the combustion chamber. You can pull the spark plugs and spin the engine over in hopes that if there is something in the cylinder it will be blown out the spark plug hole. If the object is large, it may hammer the spark plug. This will at least let you know which cylinder the knocking noise is coming from. If you have a bore scope you can look inside the cylinders and see if you see anything that might have fallen in.

Okay will do that today thank is this usually common when you change the fuel injectors?
Not really, but then again, I always use air pressure to blow away any debris around the fuel injectors before removing them. Hopefully it will clear itself and won't require you to remove the cylinder head. Remember Murphy's Law.

Okay just went to car junkyard and buy a new fuel injectors rod and went to auto zone and bought new injectors the computer that i plug in it said 123 that misfiring would those 3 make a knocking sound? Dont want to remove everything if not necessary i bought the car for 550 spent 880 on labor and 800 for parts but mostly the suspension i been fixing the minor thing that i can do i got that car cause it’s somewhat easy for a female to put there hands on but now im kinda scared
