My daughters 96 2.2 accord stared running bad last week. It has several codes.
P1491. P0135. P0301. P0303. P1300. It was not getting spark ar #3 I replaced plug wire fixed problem. Still makes no change when pulling wire off plug. Compression is within acceptable limits injector sounds a little weaker than others with stethoscope. Thinking of checking screen in injector for blockage. Any other suggestions, or something I missed other than O2 sensor code?

 

Update, I have some used injectors I changed #3 out it ran much better for a short period then right back to rough idle and dying. Swapped out with another same result. Any thoughts?
