Truck runs but spitts and sputters and misfires, has codes P0175, P1312, P0300, P0155 showing. Have changed out the MAF changed the plugs, replaced O2 sensor on bank 2 sensor 1 have used cleaner on the throttle body. Have used injector cleaner in gas and used heet gas dryer also. I have a teck working on it now and he said that he found a jumper wire at the computer on the brown wire did not know at this time where it went. Do you have any suggestions? Car smooths out and runs fine some of the time afer it warms up but not great.
