Car is running like crap can't figure out why!!!

Ok this is what you need to do. Turn the car on and have it running. Then remove the spark plug wires. One at a time. Start with 1 then 2 etc. if u notice the motor starts jerking more. Put the wire back in. Go to the next one then next one. Until you don't see a change in the motor. If this works. This will show you witch fuel injector is failing on you. Kade injectors suck and fail often. Dont drive your car like that you'll blow motor.

sorry for the late response. iv checked everything, i also noticed my knock sensor was unpluged but is still running like crap. i ran the ecu codes and came back with
12-mass airflow sensor circuit
34-knock sensor
35-egr temp sensor
41- air intake temp sensor
82-crank shaft position sensor

i just clean the MAF and car still runs kinda like crap. it idles fine and still drives good but every now then (daily) it bucks and loses power.
as to everyone else who responded, plugs are brand new and gaped to .40, i dont have any vacuum leaks cus i can still get down on the throttle. i heard that the "coolant temp sensor" might cause the car to run crazy while cruising

address these issues first. Try a different maf. Get another knock sensor and install it. If its the original sensor theres a good chance its no good. Egr temp sensor is on the intake manifold between runner number 2 and 3. Air intake temp sensor is on the airbox. Crankshaft position sensor is at the back of the motor at the top where the tranny meets the block. Is the wiring harness all in tact? Thats a lot of codes for the ecu to be throwing, seems like its been neglected severely or you have wiring issues.

never do that, it can damage the ignition system
