need some help my o2 ultra starts an idles fine, going thru the gears it spits an sputters like its starved for fuel an occassionally runnin on one cylinder intermittently then run good for a few seconds then back. i pulled the tank and fuel pump, checked the pickup, changed the fuel filter still runnin rough. going to unplug the temp sensor tonite and see if that makes a difference and check the front injector harness connection, heard they can be an issue. any ideas anyone can give would be appreciated

 

I would continue with the injector harness definatly sounds like that, try wiggling the injector wires while it is running and see if you can't get it to duplicate

 

that was it the injector harness for the front cylinder, i just pushed it on to make sure it was in all the way ran bout 40 miles without a burp, but is there a repair that i need to do to that connector so it doesnt happen again?

 

You need to get the pins for the connector and then lengthen the wire and replace the pins. The tight harness sometimes causes the wire to pull from the crimp on the terminal.

 

Also don't forget to check your motor mount too. That can cause excess movement in the motor pulling on the harness
