Q: step 1 use a long handle screw driver put it on each injector you should hear a distintive tapping as the injector fires. if one or two are week you will notice it right away. run a pressurized fuel rail cleaner follow the directions. recheck injectors if all is well thet was your problen if an injector does not sound right replace it. also buy an o-righ kist and replace all the injector o-rings while you have them pulled. -- coasty remove the spooge to reply i have 96 dakota 3.9 automatic that gives me less fuel mileage than what i believe i should be getting. i have ensured that the plugs are in good shapethe plug wires are new tires properly inflated drive with a light foot i have changed both oxy sensors. the truck runs fine and the obd ii is not generating any trouble codes. the truck recently passed the calif smog test and passed by a very wide margin. i have ran liquid injector cleaner in the tank several times. i obtained a davis carchip device so i could get a printed record of what is happening in regard to obd readings. what i found out is that fuel system #2 runs in open loop for a few minutes while the coolant temp is coming up but fuel system #1 is staying in open mode all the time. now i am an old shade tree hobby mech since model a fords were a common sight on the streets. until now i havent given much effort to understanding the obd system but i now would like to increase my knowledge in that area hence putting out the bucks for the davis carchip. my guess and correct me if i am wrong is that fuel system #1 refers to the injectors on bank #1 and fuel system #2 refers to the injectors on bank 2. can anyone confirm this. would a dirty or clogged injector in bank #1 cause it to remain in open loop is now the next logical step to have a professional cleaning of the injectors. oldtimer .
