was driveing along one day and the check engine light comes on do a ignition code check says code 43 Cylinder missfire not enough info so get a code reader and it tells me no# 5 cylinder is the bad one so i do the easy stuff first ...plug /plug wire /had a spare coil change that nothing did injector cleaner twice still no good so i did the injector still running bad so i was feeling the plugs at the injectors and noticed there was no ticking at the number 5 injector thinking it was a bad connection i replaced the harness lead to the injector still no go now in stumped and answers to my issue ?

 

Do a compression test on the cylinder. You could have a flat cam or a broken rocker tower.

 

compression test says on all front cylinders’ is 90 to 95 on first stroke 110 to 120 second stroke and 130 psi on 3rd on all cylinder’s with the issue cylinder being the strongest of all

 

also removed valve cover and all is ok every thing going up and down

 

went to dealor told them my issue and was told that computer might be faulty So what would happen if i went to wreckers and swapped computers with same year model etc
