cold cylinders, possibly miss firing cylinders??

Did you program the trim codes for each injector ?

 

Now this is really jack leg but you asked. On a 2505 or maybe a 9105 Terragator my prolink connectors would not plug in.
I wish I had kept records but I was in a pretty poopy situation and it was hot. I used meter on A/C I thank.
Am unsure of the scale I was on but compared the reading on all cylinders. The misfiring cylinder had a reading off from the rest. Do not recall how but decided it was the harness under the valve cover. I thank there are two but that fixed the problem. Those two cylinders may share the same ground.
May the force be with you!

 

Have you drove it yet?

 

Those temps are not that far off. Belive it or not. 5 and 6 cylinders are the last cylinders to recive fuel from the fuel passage. Like spsauerland asked. Have you drove it yet ? Does it have an actual misfire ? When you changed harness did you install the connector tabs on the correct injector (position) ? The tabs are numbered for what cylinder.....you may not even have an issue.

 

No since in chasing a problem if you don't really have one.
