Alright the codes i get are 12 and 55. Also i found a connection not plugged into anything. Its on the same side as cylinder 8, its on the same harness as fuel injectors 6 and 8. I labeled everything before i disconnected it so im wondering if anything was plugged into it to begin with. Its a 2 terminal with a green seal boot.
I ordered a new o2 sensor for my truck and should be here monday. Also another symptom i am having is if i rev the rpms up good its almost wanting to stall when it returns close to idle speed. I tried doing a propane vacuum test without any luck (out of carb cleaner) going to retry once i get carb cleaner.
does your truck have a/c? i think that plugs into some type of vacuum control or something at the back there. it might be hiding under the spark plug wires.
It has a/c, Im going out to work on it tomorrow an i will dig around and see if i can find a connection. There is a vacuum control but its on the driver side. I will replace the oxygen sensor and let you know if that changes anything. Another thing i was wondering if it could be a bad seal on the injector o-rings that could be causing all my problems, i had troubles getting em in.
